Subject: Case-sensitivity goals, policy and implementation

I think there are exactly two behaviours which can be easily explained to
users:
1. Everything is case-insensitive.
2. Everything is case-sensitive.
All other variants introduce rules and exceptions from the rules. I hate
exceptions - they make the rule invalid.
The variant (1) was popular long ago; however, all modern programming
languages use (2). And I am sure that case-sensitivity is useful - it is
easier to invent appropriate identifiers for all concepts of the problem,
without unnecessary complications.
So, I am for absolute case-sensitivity everywhere, without exceptions.
How to implement this in common lisp is a separate question.
