Calls a Callable Object with the arguments from a Sequence. The result of the call is ignored.

The first template parameter can be specialized explicitly to avoid copying and/or to control the const qualification of a function object.

For pointers to class members corresponding object can be specified as a reference, pointer, or smart pointer. In case of the latter, a freestanding get_pointer function must be defined (Boost provides this function for std::auto_ptr and boost::shared_ptr).

The target function must not be a pointer to a member object (dereferencing such a pointer without returning anything does not make sense, so it isn't implemented).
