Subject: Re: Confused about variable "declarations"

I'm was quite fond of "leaky" since I didn't have a good word for it
before. But you are right, I suppose. "leak" is usually a bad thing in
boats, birth control, and programming. For instance, who would to
apply "leaky logic" algorithms.  I can definitely see why they went
with "fuzzy logic" instead of "leaky logic". How about "fuzzy scope"?

Of course, this could make one think of "cuddly scope", which is also
probably accurate when it comes to Ruby (in fact, I noticed one of the
Japanese Ruby books on Amazon had a bunny rabbit on it- it was paired
with the Ruby Hackers Guide (RBG), so I assume it was Ruby- I don't
read or speak Japanese).

Of course, if we doing lisp, it would probably be called "transitive
dynamic semi-lexical scope transclusion" or something like that ( and
no, I have no idea what I just said, if anything).

Regards,
Nick
