Changes from Raphael Manfredi <Raphael_Manfredi at pobox.com> to

=head1 NAME

Callback - object interface for function callbacks

=head1 SYNOPSIS

	use Callback;

	my $callback = new Callback (\&myfunc, @myargs);
	my $callback = new Callback ($myobj, $mymethod, @myargs);
	my $callback = new Callback ($old_callback, @myargs);

	$callback->call(@some_more_args);

=head1 DESCRIPTION

Callback provides a standard interface to register callbacks.  Those
callbacks can be either purely functional (i.e. a function call with
arguments) or object-oriented (a method call on an object).

When a callback is constructed, a base set of arguments can be 
provided.  These function arguments will preceed any arguments added
at the time the call is made.

There are two forms for the callback constructor, depending on whether the
call is a pure functional call or a method call.  The rule is that if the
first argument is an object, then the second argument is a method name to
be called on that object.  Method resolution happens at the time the Callback
