Right, in my, admittedly radical opinion, all cases where the programmer
sees two things for which he is tempted to use the same name (but cannot!),
indicate some problem. Apart from poor design it could be a language
problem as well. Like when an entity is introduced, which should better be
anonymous or inferred.

Consider T and class T. In Ada T'Class is inferred, against the named
equivalence otherwise typical for it. One could have chosen in Ada 83
spirit:

   type T is tagged ...
   type T_Class is class of T;

but then one would have a problem, how to name the class of T's?

Another example:

   Line : array (1..80) of Character;

no need to name the singleton's type, no problem to name that type.

I don't like _Type, _Ptr, _Ref, but I am using them. (:-))
