Std :: bind with explicit return type

Question

One version std::bind

allows the caller to provide an explicit return type:

template< class R, class F, class... Args >
/*unspecified*/ bind( F&& f, Args&&... args );

What's a good example when you can use (or be forced to use) this version std::bind

?
