The 'classical' invocation style is not allowed because it would 
make the language grammatically ambiguous. Without semantic 
analysis, the compiler would have no way of knowing whether 
`foo!(int, int)` was intended to refer to the template instance 
foo!(int, int), or the eponymous member foo!(int, int).foo.
