Cannot create field X due to type mismatch

```haxe
class Test {
static function main() {
trace("Haxe is great!");

var myTransform = (s:SomeType, v:Float) -> {};
var g = new TypedGroup();
g.multiTransformChildren([myTransform], [10.0]);
}
}

class SomeType {
public function new() {}
}

class TypedGroup extends SomeType {
public function new() {
super();
}

public function setThings(value:Float) {
var callback = (obj:SomeType, v:Float) -> {}
multiTransformChildren([callback], [value]);
}

@:generic
public function multiTransformChildren(callbacks:ArrayV->Void>, values:Array):Void {}
}
```

Tested on 4.3.3 and 5.0.0-alpha.1+dec37b3 with the same results.

Original problem was found in flixel, so maybe it is not the Haxe but how flixel is used - if I remove `generic` from `multiTransformChildren` then it compiles. Maybe #10635 is related.
