Gee, ya think so???

I've seen two very common case conventions set into stone in programming
standards documents on Ada projects, both at the same company.

One group demanded that reserved words be all upper case, and that
identifiers be lower case or mixed case.

Another group demanded that reserved words be all lower-case and identifiers
be all upper-case.

Somehow, neither of these groups had ever heard of the psychological studies
that show that mixed and lower case are easier for humans to read.  You'd
think some of them never even heard that lower case HAD been invented.
