the ugly template keyword is necessary because _S_fwd_arg() itself is
a function template, not because it's a member of a class template.
Moving it to the impl classes would duplicate it, without getting rid
of the template keyword.

Thanks for looking over the patch though, I was wondering if anyone
had seen it ;-)
