Subject: Anonymous Classes Vs. Singleton Methods

Hi all,

I have an object which I'd like to extend with a number of methods that
will only belong to that specific object. Is it better to use singleton
methods:

def foo.method1
	...
end

def foo.method2
	...
end 
.
.
.

and so on, or is it better to use an anonymous class:

class << foo
	def method1
		...
	end
	.
	.
	.
end

Is there any (dis)advantage to either way of doing, in terms of
speed/memory etc or internally are they in actual fact the same? At the
moment I'm using anonymous classes purely for aesthetic reasons.

Thanks in advance,
Farrel Lifson
