Well, our brains are probably not compatible, because I think most case-
sensitivity arguments I've seen this far are totally bogus.  (Which is a bit
scary, because I've always thought that Python should remain case-
sensitive, and that things like this are best handled by smart development
environments.  I'm beginning to wonder if I'm wrong ;-)

The Alice study only proves that users can memorize the case conventions
used in a single specific library (in this case, the Alice environment), not that
they won't get into trouble again when they stumble upon a library that uses
different conventions.

PS.  I've scanned the HCI literature I have access to, but they all seem to
consider "case-sensitivity is a really lousy idea" as a law of nature.  If any-
one has better references than "it has been known for decades" and "most
programmers simply don't care about ordinary humans", please post pointers.
