With the small distinction that there are case insensitive, case
preserving and case sensitive file systems, whereas identifiers are
always case sensitive.
My experience is that it's hard to get case right on the former two
types of systems because you don't have real testing. That's why I'm in
favor of all lower case file names.

I think it could cause confusion, but it should be so easy to do that
you'll just be able to try it out. Just allow '-' in the mid of an
identifier, and longest token matching takes care of the rest. Since
whitespaces terminate LTM, they automatically disambiguate operators.
