This code fails with
Error: recursive template expansion for template argument bar!(int)
Now, I agree it is recursive, but it is not infinitely recursive, so
there shouldn't really be a problem.
Is this a bug? Is there a workaround?
It's lazily recursive. Meaning, it *is* infinitely recursive, but the
compiler does not have to evaluate all the recursions until they are used.
I'm not sure it should be disallowed, but it's definitely on the edge. Do
you have some real-world case for this? If you want to get something like
this fixed, you'll need a good example, not an academic one.
