forwarded abstract fields are not available through a constrained type parameter

[nadako]

@:forward(forwarded)
abstract A({function forwarded():Void;}) {
	public function defined() {}
}

function f<TA:A>(v:TA) {
	v.defined(); // works
	v.forwarded(); // doesn't work
}

(this is not a regression)

also, forwarded shows up in the completion :)
