You can do this now -- in a JSNI method:
static void bar(int arg) { ... }
var f = @org.example.Foo::bar(I);
You can then pass/return it to Java/JSNI code as a JavaScriptObject, or
directly to external Javascript that looks for a function.

You have to have a JSNI method to do this now:
private static native JavaScriptObject callFunc(JavaScriptObject func, int
arg) /*-{
func(arg);
}-*/;
