I'll make the fixes based on the comments, but had question about the
FunctionTypeInfo in the meantime.

Hmm, I'm not sure if we'd run into that case because I don't believe we can
have a `concept` specified as a typedef (check is yet to be added) and a check
exists for being in a non-namespace scope. Do you think a check should still be
added verifying that the FunctionTypeInfo exists?
