It is, and always has been my opinion that case sensitivity is a bad thing
because it creates more problems than it solves.

Instead of repeating myself I shall point you to

Great. So your compiler did not allow you to reference anyhing in a
different case. But did it actually allow you to create several variabes or
methods with exactly the same spelling but different case? If the language
does not allow it, then there is no real problem. It only becomes a problem
when the language DOES allow it.

Most languages don't use case to identify wheter something is a constant,
variable, function, or method, so the use of case is irrelevant.

But people won't complain unless they hit problems, and I've seen complaints
from programmers who have suddenly been hit with a bug that turns out to be
case-related. I still hold the opinion that case sensitivity causes problems
instead of solving them, and I have seen no evidence to the contrary.
