Does not compile (compilation error is in a comment in the source). Difference
from `works.cpp` is that class and function are in a namespace.

Clang fails to find the default template argument, but only if it's in a
namespace. This seems like a weird corner case that may have been missed in
tests but has come up for me. GCC is able to compile it.

I have attached two nearly identical versions. One (works.cpp), does *not* have
anything in a namespace. The other (broken.cpp) has all of them in a single
namespace (N).
