Jexl seems to implement 'div' as simple division, instead of the pair with 'mod'. I'd like to correct it. Was this a design though, for 'div' to be divison, and not the typical div operator?

It's supposed to be /. There is supposed to be a pairing of / and div,
% and mod as far as I can read the JSTL spec.
Yah, the semantics of '/' seem right, in that they perform division where ( int / int ) yields a float.
But 'div' should do real div, at least in my mind (though, I can understand if you're following a broken spec) and yeild an integer from (int div int), but it doesn't.
I have no real knowledge, but am guessing that the tokens 'div' and 'mod' are there to give people an alternative to having '/' in XML-ish looking things.
So, we have 2 ways to mod, 2 ways to divide, an 0 ways to div.
However, if you need both / and the real div, we should consider it.
It's a break from JSTL, something that worries me. (Although it can be
fairly argued we aren't compatible, I am hoping to get that way...)
I think division is obviously needed, but I don't know if we need 2 tokens to do it. Having 'div' to what most folks consider to be 'div' would be a Good Thing.
Then we should shoot 'mod' if we are going to break.
Hm. Would a idiv or something be sufficient? We'd have to document.
I'm going to re-read the JSTL spec to see if I messed this up.
