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.
