abstract @:to not considered for static extensions

Hi folks,

is the last expression in this example supposed to compile?

using Test.Usings;

class Usings {

    public static function withInt (m:Int):Int {
        return m;
    }

    public static function withString(m:String):String {
        return m;
    }
}

abstract Zapp(Int) to Int {

    @:to public function toString ():String return "";

}

function main () {
    var z:Zapp = cast null;
    z.withInt(); // works
    var y:String = z; // works
    z.withString(); // using fails to compile
}

Well, that's kinda by design: #5924

I guess a "smarter" way to deal with the problems I raised would be to first resolve extensions on the type itself and only then on types compatible via @:from/@:to casts. Although that still means that down the line the addition of more casts can affect the second selection pass in existent modules, either breaking things or silently selecting another extension.

Ah yes, thx for clarification.
