template<class T_return>
class sigc::slot< T_return, nil, nil, nil, nil, nil, nil, nil >
Convenience wrapper for the numbered sigc::slot0 template. 
See the base class for useful methods. This is the template specialization of the unnumbered sigc::slot template for 0 argument(s), specialized for different numbers of arguments This is possible because the template has default (nil) template types.
- Deprecated:
- Please use the syntax similar to that used by std::function<>: 
Convenience wrapper for the numbered sigc::slot# templates.
