You're right. It's simply ugly that the compiler think that it needs to
instantiate every class recursively, when the classes are never used. It'd be
nice to get rid of that (Dummy=void) hack, which has the nasty side-effect that
it allows you to instantiate it as a template, for example as
bar!(int). But it's not a bug.
