Despite that this SINGULAR case where case-sensitivity would solve the
problem it COMPLETELY overlooks the many cases where case-sensitivity
[and using it to conceptually-overload an identifier] introduces Bad
Things.

Consider this code:

Type THIS is private;
Procedure this( This: out THIS; THis : in THIS; THIs : in out THIS );

Upon *hearing* your boss say "There is a problem in the program with
this; fix it." what "this" is he talking about?
{ Yes, I realize that no *sane* programmer would produce something
like this, but isn't the continued popularity of C/C++ proof that
there is a large chunk of programmers who are not sane? ;) }
