This is mostly useful for ensuring the code is invoked at end of scope. This module is not a part of autodie's public API. .PP This module is directly inspired by chocolateboy's excellent Scope::Guard module. .SS Methods .IX Subsection "Methods" \fInew\fR .IX Subsection "new" .PP .Vb 1 \& my $hook = autodie::Scope::Guard\->new(sub {}); .Ve .PP Creates a new \f(CW\*(C`autodie::Scope::Guard\*(C'\fR, which will invoke the given sub once it goes out of scope (i.e. its DESTROY handler is called). .SH AUTHOR .IX Header "AUTHOR" Copyright 2008\-2009, Paul Fenwick <pjf@perltraining.com.au> .SH LICENSE .IX Header "LICENSE" This module is free software. You may distribute it under the same terms as Perl itself.
