You've got it the other way around.  If func is an instance method
(non-static method) of a class, &func is a delegate, not a function.

It can't evaluate &func at compile-time because there is no way to
create a delegate at compile-time.  You need an instance to create a
delegate, which you can only create by using 'new', which only works
at runtime.
