The nullary overload of the call operator can be removed by setting the

second template parameter to <code class="computeroutput"><span class="keyword">false</span></code>,

second template parameter to <tt class="computeroutput"><span class="keyword">false</span></tt>,

which is very useful if the result type computation would result in a compile

error, otherwise (nullary call operator's prototypes can't be templates

and thus are instantiated as early as the class template).

The type of the target function is allowed to be const qualified or a reference.

Const qualification is preserved and propagated appropriately. In other

words, only const versions of <code class="literal">operator()</code> can be used

words, only const versions of <tt class="literal">operator()</tt> can be used
