SYNOPSIS

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

DESCRIPTION

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.
