| This is too specific for Matthias' purposes (doesn't work on | containers of iterators or smart pointers). Maybe something like: | | template< class Fun > | struct indirect_fun | { | indirect_fun( Fun f ) : fun(f) | { } | | template< class T > | typename | result_of<Fun(typename pointee<T>::type)>::type | operator()( T const& r ) const | { return fun( *r ); }
yeah, this is good stuff, mind if I borrow it?
