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
|

for a target function object that is const or, if the target function object
|

is held by value, the adapter is const - these semantics have nothing to
|
||||
do with the const qualification of a member function, which is referring
|

to the type of object pointed to by <code class="literal">this</code> which is specified
|

to the type of object pointed to by <tt class="literal">this</tt> which is specified

with the first element in the sequence passed to the adapter).

If the target function is a pointer to a class members, the corresponding

object can be specified as a reference, pointer, or smart pointer. In case
