It's funny; but the early programming languages were designed by
mathematicians.  Trust me, if they'd been able to use ∧ for and, and ∨
for or, they would have :)  On a few systems, they actually *did*.  I
think programmers use "simpler" notation simply because we're limited to
what we can bang out on a keyboard, and mathematicians aren't.

(In fact, mathematicians seem to *love* inventing new symbols: the guy
who invented lambda calculus originally wanted to introduce a new
symbol.  But when it was sent off to be published, the typesetter
mistook his new symbol for a lambda (λ), and it kinda stuck :P)

Incidentally, I think the symbols used in mathematics are better if
they're available since they're pretty unique, and stand out even
better.  An interesting thing to try is writing up some CWEB code: it
converts all the &&s and ||s to ∧s and ∨s in the TeX documentation :3

I prefer using names if the names are short and meaningful.  It makes
code that little less cryptic.  As long as you don't end up with insane
symbols like #!@$? actually *meaning* something, it all works either way.

Similarly, one of the reasons I hate Java is because

Ah well, each to their own, I suppose.
