NAME
Aspect::Guard - General purpose guard object for destroy-time actions
SYNOPSIS
SCOPE: {
my $guard = Aspect::Guard->new( sub {
print "Goodbye World!
";
} );
}

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.
