There is a 'typename' missing, but that won't help AFAICS.

The compiler has no idea how to deduce U as - depending on U -
param_type could change. What happens if two different U's would be a
valid match? IIUC the standard forbids type-deduction is these cases to
avoid non-portable code, so if any other compiler would work, it would
IMHO not be standard conformant code.
