Hi, I'm not sure if this issue already exists, or if there are any workarounds. If I create an abstract wrapper for an enum, and the abstract has implicit cast function (@:from), the compiler doesn't recognize the implicit cast inside Map literals.

http://try.haxe.org/#aaaFa

enum ValueEnum {
  VString(v : String);
  VInt(v : Int);
}

abstract ValueAbs(ValueEnum) {
  public inline function new(v : ValueEnum) {
    this = v;
  }

  @:from
  public static function fromString(v : String) : ValueAbs {
    return new ValueAbs(VString(v));
  }

  @:from
  public static function fromInt(v : Int) {
    return new ValueAbs(VInt(v));
  }
}

class Test {
  static function main() {
    // compiles and works
    var myMap = new Map<String, ValueAbs>();
    myMap.set("one", "some string");
    myMap.get("one");

    // Doesn't compile
    var myMap2 : Map<String, ValueAbs> = [
      "one" => "some other string"
    ];
    myMap2.get("one");

  }
}
