Not really. The `template' keyword should only be required below in
case the type of `f' was dependent on template arguments. But this is
not the case, so `template' is optional. Using it is just a
work-around for GCC.

This is not a gcc bug, your code is invalid. Replace
template <typename _type>
_type moo( const foo& f ) { return f.cast_foo<_type>(); }
with
template <typename _type>
_type moo( const foo& f ) { return f.template cast_foo<_type>(); }
and your code will compile.

The compiler fails with a parse error if a template function tris to instatiate a template using one of its template parameters as an argument.
>How-To-Repeat:
The following code fails to compile with the following error:
foo.C: In function `_type moo(const foo&)':
foo.C:10: parse error before `>' token
test file: foo.C
----------
struct foo {
template <typename _type>
operator _type() const { return _type(); }
template <typename _type>
_type cast_foo() const { return *this; }
};
template <typename _type>
_type moo( const foo& f ) { return f.cast_foo<_type>(); }
int main() {
return 0;
}
