NAME

Sub::Call::Tail - Tail calls for subroutines and methods

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.
