Should .bind() be forwarded for abstracts?

```Haxe
package ;

class Main {

public static function main() {
var f:AbsString->Int> = (a, b) -> a + b.length;
var b = f.bind(_, 'hello');
trace( b(1) );
}

}

@:forward
abstract Abs(T) from T to T {}
```

Throws the following error:
```
Main.hx:7: characters 19-23 : Abs<(Int, String) -> Int> has no field bind
Main.hx:7: characters 24-25 : Unknown identifier : _
```
