Description:
------------
Currently the callable name can only be fetched using is_callable and a 3rd argument. However this doesnt seem appropriate when using callable type hints..

get_callable_name (just like get_resource_type) would be in place imho.

Test script:
---------------
<?php
function foo(callable $bar) {
    $name = null;
    $name = is_callable($bar, true, $name);

    // vs

    $name = get_callable_name($bar);
}

Using is_callable() to get the name can be simplified:

  is_callable($bar, true, $name);
  
vs.

  $name = get_callable_name($bar);
  
That's not much of a difference. And of course, it is possible to
to write the desired function in userland code.

If you're still interested in having get_callable_name(), please
forward this request to the internals mailing list[1], since this
feature needs to be discussed (besides that it's trivial to
implement the function in userland, the name wouldn't fit to our
naming scheme).  Thanks!  For the time being, I'm suspending this
ticket.
