General purpose guard object for destroy-time actions
SCOPE: {
my $guard = Aspect::Guard->new( sub {
print "Goodbye World!\n";
} );
}
# Prints here as it exits the scope
The Aspect::Guard class shipping with Aspect is a convenience module for creating \*(C`CODE\*(C' based objects that execute when they fall out of scope.
It's usage is effectively summarised by the synopsis.
my $guard = Aspect::Guard->new( sub { do_something(); } );
The \*(C`new\*(C' method creates a new guard object. It takes a single \*(C`CODE\*(C' references as a parameter, which it will bless into the guard class, which will execute the code reference when it's \*(C`DESTROY\*(C' hook is called.
