Please pay particular attention to the alternatives, I'm not sure that I have captured everything important we considered in #995 . |

I have a draft PR #2866 for updating the syntax in the design docs, if you would like to see how this looks in a number of examples. |

There was a problem hiding this comment.
Approving on behalf of leads. This reflects decisions from prior leads issues, with a scope reduction for require that @chandlerc and I are both happy with and that seems to generally improve consensus. Thanks!

This includes:
- Syntax changes from this chart:
| Before | After |
| ------------------------------- | --------------------------------------- |
| `class D extends B { ... }` | `class D { extend base: B; ... }` |
| `external impl C as Sub;` | `impl C as Sub;` |
| `class C { impl as Sortable; }` | `class C { extend impl as Sortable; }` |
| `adapter A for C { ... }` | `class A { adapt C; ... }` |
| `adapter A extends C { ... }` | `class A { extend adapt C; ... }` |
| `interface I { impl as J; }` | `interface I { require Self impls J; }` |
| `interface I { extends J; }` | `interface I { extend J; }` |
- Dropping the syntax for conditionally implemented internal interfaces.
This does not include:
- terminology changes from #2760 ("internal" and "external")
- changes to code, such as explorer, toolchain, language grammars, or other tooling

This reflects changes from a number of approved proposals: - #920 : concrete statements about orphan and overlap in Carbon - #2138 : "generic" -> "checked generic", "template" -> "template generic" - #2188 : binding patterns are forbidden in type position - #2360 : "type", "facet type", "facet". Note: I am not using the term "generic type" from #2360 since that meaning conflicts with the generally accepted meaning of "generic type" of a type with a compile-time parameter. - #2760 / #2770 : internal/external impl -> extending impl - #2964 : "symbolic constant" and "template constant" --------- Co-authored-by: Geoff Romer <[email protected]> Co-authored-by: Richard Smith <[email protected]>

Includes proposals: - #990 - #2188 - #2138 - #2200 - #2360 - #2760 - #2964 - #3162 Also tries to use more precise language when talking about: - implementations, to avoid confusing `impl` declaration and definitions with the `impls` operator used in `where` clauses, an issue brought up in #2495 and #2483; - "binding patterns", like `x: i32`, and "bindings" like `x`. --------- Co-authored-by: Chandler Carruth <[email protected]>

…4401) Note: some of this is from the principle of information accumulation, and some is from [proposal #2760](https://github.com/carbon-language/carbon-lang/blob/trunk/proposals/p2760.md#class-inheritance). Also: change terminology from "virtual override keywords" to "virtual modifier keywords", to be consistent with our other modifier keywords. --------- Co-authored-by: Josh L <[email protected]>
