Template specialisations

Hello All!

I got stuck with template specialisation, and all my books are at work, so I ask my question here.

Does somebody know how to create a template specialisation for template class template function?

For simple function it would look like this:

template< typename T >
void foo( T param ) { /* body goes here */ }

template<>
void foo( int param ) { /* body goes here */}

But when I try to do something like this:

namespace foo {
template< typename T >
class bar {
template< typename TT >
bar( const bar< TT > &r ) { }

template<>
bar( const bar< T >&r ) { }
};
}

I get an error from gcc (2.96) : explicit specialization in non-namespace scope `class
foo::bar.

How to do the specialisation here?

Thank you in advance.
