Well, speaking anecdotally, I remember years ago when I was learning to
program and I had trouble with those operators. I admit that I can't
remember exactly what the trouble was now, but for some reason I often
got them reversed.
I think that "orelse" gives a better feeling of proceeding from one test
to another. The corresponding replacement for "and" is "andalso". I
think that these names also give a hint of the short-circuiting nature
of the operators...
