[feature request] return name of current function

Hi Is there anything that is speaking against a function or a constant, that contains the name of the current function? This might be especially useful for situations like <?php function print_error($name) { echo "An error occured in ".$name; } function foo() { if ($error) print_error('foo'); } ?> where you pass the name of the function (in this case the function, where the error occurs) to another function. If there would be function or a constant to return the current name, you could simply type: function foo() { if ($error) print_error(cur_function[()]); } So if you rename the function you do not need to change the (perhaps multiple) call(s) for print_error().
