 autodie::Scope::Guard - Wrapper class for calling subs at end of scope

SSYYNNOOPPSSIISS #

         print "Hallo world\n";
     });

 This class is used to bless perl subs so that they are invoked when they
 are destroyed.  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.

 This module is directly inspired by chocolateboy's excellent Scope::Guard
 module.

   my $hook = autodie::Scope::Guard->new(sub {});

 Creates a new "autodie::Scope::Guard", which will invoke the given sub
 once it goes out of scope (i.e. its DESTROY handler is called).
