A little follow-up: after '&Foo' has been parsed, 'Parser::isTemplateArgs'
is been called. However, as the comment above that method indicates:

/*
   template.args : '<' any* '>'

   template.args must be followed by '(' or '::'
*/

which obviously doesn't account for this case where a function pointer
is passed, i.e. no terminating '('. Now I'm a bit lost. I guess the '('
constraint is used to disambigate from a relational expression, i.e. if
we drop it, we'll misinterpret other expressions. Could I simply add ';'
and ',' to the list of symbols potentially following the template args ?
May be I should have a look into the new C++ parser used in gcc 3.4...

Any ideas ? Chiba ?

Kind regards,
