OK, I went back and read the previous posts. I found exactly one
post, by Booby D. Bryant, who claimed that "a large proportion
of the bugs I've fixed in my whole life were the result of people
using identifiers with the wrong case". There were no examples,
so it's hard to evaluate how typical this might be.

Then there was one post by you, giving an example of how you
might call the wrong routine if two different packages had a
method with the same spelling but different case, and the same
argument types, whereas currently, you would be required to
disambiguate by specifying the package name. I find that less
than compelling as well - what prevents you from specifying
the wrong package, after all?

Then you have to know which one you want, and use it.
If you have objects named L00P and LOOP, you are in
the same position. But it's an odd situation to have
things of the same sort that differ only in case. It's
very seldom that I see anything like that, and I program
mostly in case sensitive languages.
