Odd regression in `from` structure.

[back2dos]

Minimal example:

package ;

function main() {
  var cfg:DialogConfig = {
    priority: 0,
    ui: (null:RenderResult),
  };
}

@:forward
abstract DialogConfig(DialogConfigData) from DialogConfigData {
  @:from static function fromRenderResult(r:RenderResult):DialogConfig
    return { priority: 0, ui: r };
}

typedef DialogConfigData = {
  final priority:Int;
  final ui:DialogUi;
}

@:callable
abstract DialogUi((close:()->Void)->RenderResult) from (close:()->Void)->RenderResult {
  inline function new(f) this = f;
  @:from static function fromRenderResult(r:RenderResult)
    return new DialogUi(_ -> r);
}

abstract RenderResult(String) to String from String {}

This broke somewhere between a8f2911 and fa582e3. Can't track it down any further as there are no nightlies in-between, but FWIW it looks like it might be related to 5345c4d.

Changing the last line to typedef RenderResult = String; makes it compile too.
