NAME

Protect-Unwind - Safe cleanup blocks, Common Lisp style

SYNOPSIS

    use Protect::Unwind;

    protect {
      goto ESCAPE;
    } unwind {
      print "This is printed no matter what happens in protect.";
    };

    ESCAPE:

DESCRIPTION

This module is just syntactic sugar around Guard. It implements an interface like Common Lisp's unwind-protect.

It only exists so that hopefully lisp programmers new to perl will find this module before they find the buggy Unwind::Protect.

Note that if your unwind forms throw exceptions the behaviour is somewhat complicated (see the Guard docs).

SEE ALSO

Guard is a correct and efficient perl unwind-protect implementation which is why this module uses it.
