Hm, could you show an implementation? I think that the "convertible to
bool" might be a problem for classes with operator bool(), also I'm not
sure how you would detect:

is_class< int( int, int ) >::value

correctly with your approach...

What is SFIAE? Is it the

  template< typename > no_type test( ... );
  template< typename T > yes_type test( void (T::*)() );

stuff from Paul Mensonides?
