NAME
Sub::Call::Tail - Tail calls for subroutines and methods
VERSION
version 0.08
SYNOPSIS
use Sub::Call::Tail;
# instead of @_ = ( $object, @args ); goto $object->can("method")
tail $object->method(@args);
# instead of @_ = @blah; goto &foo
tail foo(@blah);DESCRIPTION
This module provides a tail modifier for subroutine and method calls that will cause the invocation to have the same semantics as goto &sub.
When the tail modifier is compiled the inner subroutine call is transformed at compile time into a goto.
USAGE WARNING
WARNING! The author does not endorse using this module for anything real. It was written primarily to demonstrate that such quackery can be achieved. Use at your own risk!
