It's not exactly a contradiction... I wouldn't allow both $foo and
$FOO in the same program. In a case-insentive language that's
allowed. I would want that completely disallowed.
That's a bit difficult in a free-form language like PHP but in
languages with variable declarations, the variable would have to match
the declared case otherwise it would be an error.
