Subject: Re: redefining splat?

I would agree with Matt, if you are trying to redefine the splat
operator (is that really what we're calling it? neat), with the .to_a
or .to_ary to return a class instead of an array, you should make sure
that the class looks enough like an array that it wouldn't break
someone's expectations later.

It might not make a big difference now, but should someone need to
touch your code later, even if that person is yourself, you will save
many headaches by not being overly trixy.
