Uhm... Aikar, did you forget that //calc isn't blocked? Did you plan it that way, or did I find something that you missed?
Like Stew said, most calculations are trivial for a computer to do. But you'd probably want to add safeguards, just in case someone tries to abuse it, like setting a max length for the formula.
Being a maths student, I just so happen to have a calculator almost permanently on my desk... nice idea but I doubt I would use it, as it would be just as easy to use an actual calculator. But for other users +1!
I'm pretty sure //calc is one of the bits of WE that can't be permission locked, and is definitely a good idea actually.
True, but is there a 1.8 version of that, then? I asked about it, but minecraftforums deleted my comment and warned me for update spam...
