Not quite true. It does not exist in ALL languages (Visual Basic,for
example, is case *preserving* not case *sensitive*) and in some languages it
is only partially implemented (PHP, for example, is case sensitive with
variable names but *not* for function names).
To say that it is *the standard* is therefore incorrect. It may be with some
people but not for others. There are *some* people who wish to extend cas
sensitivity in PHP to include function names forno goodreason other than
*they* consider it to be *the standard*. Phooey!
To say that case sensitvity is not a problem if all names are written in
consistent case does not disguise the problem that if you are not aware of
the case sensiive nature of the language, or if you *accidentally* use the
wrong case, then this can cause problems that are difficult to track down.
Even worse, the *deliberate* use of using different case with different
instances of the same variable or function name is a surefire way of
producing obfuscated and unmaintainable code.
Standards to get around this problem are irrelevant if the *accidental* or
*deliberate* use of this *feature* can produce unmaintainable code. It is my
view that this feature should *NOT* be extended.in *ANY* language, in fact
it should be phased out for the simple reason that it serves no useful
purpose. Case sensitivity does not *solve* any problems therefore it is a
solution that is not required. Instead it can, if abused, cause serious
problems, and should thereore be removed. In my humble opinion, that is.

Then you are blind to the logic of my arguments.
