NAME

Aspect::Guard - General purpose guard object for destroy-time actions

SYNOPSIS

  SCOPE: {
  
      my $guard = Aspect::Guard->new( sub {
          print "Goodbye World!\n";
      } );
  
  }
  # Prints here as it exits the scope

DESCRIPTION

The Aspect::Guard class shipping with Aspect is a convenience module for creating "CODE" based objects that execute when they fall out of scope.
It's usage is effectively summarised by the synopsis.

METHODS

new

  my $guard = Aspect::Guard->new( sub { do_something(); } );
The "new" method creates a new guard object. It takes a single "CODE" references as a parameter, which it will bless into the guard class, which will execute the code reference when it's "DESTROY" hook is called.
