NAME

Sub::Current - Get the current subroutine

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.

Note: on perl 5.16.0 and later you can use the built-in __SUB__ instead, enabled by the pragma use feature 'current_sub'.
