Calls a <a href="../../concepts/callable.html" title=" Callable Object">Callable
Object</a> with the arguments from a <a href="../../../sequence.html" title="Sequence">Sequence</a>.
The result of the call is ignored.
</p>
<p>
The first template parameter can be specialized explicitly to avoid copying
and/or to control the const qualification of a function object.
</p>
<p>
For pointers to class members corresponding object can be specified as
a reference, pointer, or smart pointer. In case of the latter, a freestanding
<tt class="literal">get_pointer</tt> function must be defined (Boost provides
this function for <tt class="literal">std::auto_ptr</tt> and <a href="http://www.boost.org/libs/smart_ptr/shared_ptr.htm" target="_top"><tt class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">shared_ptr</span></tt></a>).
</p>
<p>
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).
