Uses the subexpression syntax to allow for dynamic partial lookups. Ex:

{{> (helper) }}

Fixes #933

@mmun Would love your feedback here as this introduces AST changes, but now is the time to make them.

I don't think introducing a new Expression is the solution here. A PartialExpression should be substitutable for any Expression but they don't make sense inside a Param or Hash value in a mustache, (you can't get there syntactically, but leaving it as a possible AST seems bad).

Maybe just extend the the partial production to understand nested sexprs in the first slot?

partial
  : OPEN_PARTIAL OPEN_SEXPR sexpr CLOSE_SEXPR param? hash?  CLOSE -> ...
  | OPEN_PARTIAL sexpr CLOSE -> new yy.PartialStatement($2, yy.stripFlags($1, $3), yy.locInfo(@$))
  ;

I am starting to think that the sexpr production should include OPEN_SEXPR and CLOSE_SEXPR and each of the the statements should explicitly list out the inputs they accept.

@kpdecker
Update for proposed SubExpression dependency break
999da73 
Avoids parsing against SubExpressions and instead inlines the content that a subexpression otherwise would have. This can still be based via duck typing so should not add much overhead to the compiler.

@mmun updated the AST spec doc to remove direct SubExpression references in statements. This simplifies a few things, but complicates others. LMK if we are we on the same page there and I'll update the code to follow this.

👍 👍 This seems very reasonable to me.

It's a bit of a bummer that mustache/block get a bit more complicated but I think it's worth the flexibility.

Dropping isHelper is nice too. SubExpressions are now guaranteed to be helpers.

They become more complicated, but they are duck typing data that was already there. The way that I'm thinking about coding it, it's actually less complicated in the compiler (no intermediate sexpr block for the same content) at the cost of potentially having more complicated parser.

Will ping this review after the code changes are done.

@kpdecker
Avoid direct references to sexpr in statements
884bf15 
This allows us to avoid creating unnecessary AST nodes and avoids things like isHelper.

Side effect of these changes is that @DaTa functions can now have data parameters passed to them.

@mmun code changes pushed, if you are concerned about that. Looks like the library size only goes up by ~600bytes, which isn't too bad. Note that I did go the route of adding support for {{@foo bar}} as we chatted about briefly off thread.

- Expose escapeExpression on the root object - 980c38c
- Remove nested function eval in blockHelperMissing - 6f22ec1
- Fix compiler program de-duping - 9e3f824

Compatibility notes:
- The default build now outputs a generic UMD wrapper. This should be transparent change but may cause issues in some environments.
- Runtime compatibility breaks in both directions. Ensure that both compiler and client are upgraded to 2.0.0-beta.1 or higher at the same time.
  - `programWithDepth` has been removed an instead an array of context values is passed to fields needing depth lookups.
- `false` values are now printed to output rather than silently dropped
- Lines containing only block statements and whitespace are now removed. This matches the Mustache spec but may cause issues with code that expects whitespace to exist but would not otherwise.
- Partials that are standalone will now indent their rendered content
- `AST.ProgramNode`'s signature has changed.
- Numerious methods/features removed from psuedo-API classes
  - `JavaScriptCompiler.register`
  - `JavaScriptCompiler.replaceStack` no longer supports non-inline replace
  - `Compiler.disassemble`
  - `DECLARE` opcode
  - `strip` opcode
  - `lookup` opcode
  - Content nodes may have their `string` values mutated over time. `original` field provides the unmodified value.
- Removed unused `Handlebars.registerHelper` `inverse` parameter
- `each` helper requires iterator parameter

- Temporarily kill the AWS publish CI step - 8347ee2

Compatibility notes:
- A JSON polyfill is required to run the compiler under IE8 and below. It's recommended that the precompiler be used in lieu of running the compiler on these legacy environments.

Compatibility notes:
- The project now includes separate artifacts for AMD, CommonJS, and global objects.
  - AMD: Users may load the bundled `handlebars.amd.js` or `handlebars.runtime.amd.js` files or load individual modules directly. AMD users should also note that the handlebars object is exposed via the `default` field on the imported object. This [gist](https://gist.github.com/wycats/7417be0dc361a69d5916) provides some discussion of possible compatibility shims.
  - CommonJS/Node: Node loading occurs as normal via `require`
  - Globals: The `handlebars.js` and `handlebars.runtime.js` files should behave in the same manner as the v1.0.12 / 1.0.0 release.
- Build artifacts have been removed from the repository. [npm][npm], [components/handlebars.js][components], [cdnjs][cdnjs], or the [builds page][builds-page] should now be used as the source of built artifacts.
- Context-stored helpers are now always passed the `options` hash. Previously no-argument helpers did not have this argument.

[Commits](handlebars-lang/handlebars.js@v1.0.12...v1.1.0)

## v1.0.12 / 1.0.0 - May 31 2013

- [#515](handlebars-lang/handlebars.js#515) - Add node require extensions support ([@jjclark1982](https://github.com/jjclark1982))
- [#517](handlebars-lang/handlebars.js#517) - Fix amd precompiler output with directories ([@blessenm](https://github.com/blessenm))
- [#433](handlebars-lang/handlebars.js#433) - Add support for unicode ids
- [#469](handlebars-lang/handlebars.js#469) - Add support for `?` in ids
- [#534](handlebars-lang/handlebars.js#534) - Protect from object prototype modifications
- [#519](handlebars-lang/handlebars.js#519) - Fix partials with . name ([@jamesgorrie](https://github.com/jamesgorrie))
- [#519](handlebars-lang/handlebars.js#519) - Allow ID or strings in partial names
- [#437](handlebars-lang/handlebars.js#437) - Require matching brace counts in escaped expressions
- Merge passed partials and helpers with global namespace values
- Add support for complex ids in @DaTa references
- Docs updates

Compatibility notes:
- The parser is now stricter on `{{{`, requiring that the end token be `}}}`. Templates that do not
  follow this convention should add the additional brace value.
- Code that relies on global the namespace being muted when custom helpers or partials are passed will need to explicitly pass an `undefined` value for any helpers that should not be available.
- The compiler version has changed. Precompiled templates with 1.0.12 or higher must use the 1.0.0 or higher runtime.

Partials don't work with subexpressions (like they should?)
