The fact that some people choose to apply different meanings is irrelevant.
I am talking about variable and function names in computer languages. Nobody
in their right minds would deliberately create three different variables
such as $foo, $Foo and $FOO as it could create confusion and lead to a
maintenance nightmare. If that isthe case then why should the language allow
that sitatio to be created in the first place?

You agree with me? Well, I'll go to the foot of our stairs!
