Sub::Current - Get the current subroutine

    use Sub::Current;
    sub f {
	# ...
	if ($some_condition) {
	    # let's recurse!
	    ROUTINE->();
	}
	# ...
    }

Sub::Current makes available a function ROUTINE(), that returns a code reference pointing at the currently executing subroutine.

In a special block (BEGIN, END, CHECK, INIT, and UNITCHECK in Perl 5.10) this function will return undef.

Outside of a special block (that is, at the top level of a program) ROUTINE() will return undef as well.
