Future.sync() saved to Promise has sticky type on hashlink #172

Open ianxm opened 1 year ago

This works in --interp and -neko but failes on -hl. There's no problem if the promises have the same type parameters, or if they're typed as Futures even with different type parameters.

        var a :Promise<Int> = Future.sync(2);
        a.handle( ii -> trace('a ${ii.sure()}') );

        var b :Promise<String> = Future.sync("two");
        b.handle( ii -> trace('b ${ii.sure()}') );     // <-- line 10

the error is
