Computed properties on objects appear to not be supported

[NocturnalSolutions]

If an object or struct is passed to a template, you can generally access the properties on the object/struct by using {{ objectName.propertyName }}. However, this appears not to work with computed properties.

In other words, with a class like:

class foo {
  var bar: String = {
    return "baz"
  }
}

If you instantiate a foo, put it in the context dictionary, and then try to print {{ foo.bar }} in the template, nothing prints.

In my actual code, I didn't want my bar value to be an actual normal property calculated when init-ing the struct, so I ended up working around it by implementing bar as a Stencil filter.

Swift Mirror does not support computed properties, it is used to lookup properties of swift types. If you use NSObject-based types KVO will be used. There is no workaround for that, as far as I know. You could though define an extension on your type that creates a context dictionary that you use in Stencil instead of accessing properties, but that's far from a good solution.
