[eval] Instance prototype not found: haxe.iterators.MapKeyValueIterator (without abstracts) #10039

Closed Aurel300 closed 3 years ago

class Main {
  public static function main():Void foo([]);
  static function foo<T>(map:Map<T, Int>):Void for (k => v in map) {}
}

9712 seems to be about abstracts, here the issue is reproduced simply with a generic. It only errors out when `T` is the key type, with `Map<Int, T>` it works.

It's a regression in development branch. @:multitype requires type parameters to be known at compile time. That sample should error out. Here's how it looks with 4.1.4:

Main.hx:2: characters 42-44 : Type parameters of multi type abstracts must be known (for haxe.IMap<Unknown<0>, Int>)
