Do you really think so?

I think, the capical 'I' is very different from i=sqrt(-1).  ;-)

To be honest, I agreee that Ada should not adapt the concept of many other 
case-sensitive languages that capitalization (such as changing between 'I' 
and 'i') gives you two different identifiers, to be used interchangeably.

On the other hand, I would prefer the compiler to require a consistent 
casing. E.g., if you define an identifier "Ada", you are not allowed to 
spell the same identifier as "ADA", "ada", "aDa", ... anywhere else.

Or consider

   procedure P(Value: Integer) is ...
   ...

   declare
     i: Integer := 0;
   begin
     declare
       I: Integer := 1;
     begin
       P(i); -- DOES call P(1) in Ada, since Ada is
             --      not case-sensitive
             -- WOULD call P(0) in most other modern languages,
             --       which usually have case-sensitive identifiers
             -- SHOULD be treated as an error, because "i" and "I"
             --        are *different* identifiers, nevertheless "i"
             --        has been hidden by  "I".
      end;
   end;
