They're keen on using the spelled-out "and" and "or" as per iso646.h in our code, rather than the standard && and || operators. Admittedly they do look nice, and match well with our Python code. But it's weird to see them in C, and I've never seen them anywhere else on The Internet.

(If you've never seen "and" and "or" used in C, you can read about them and iso646.h here: http://en.wikipedia.org/wiki/Iso646.h)

So I'm just curious: Does anyone else use them? Either yourself or in an open-source project you've seen?
