Maybe. It's just saying (to the Ada implementer) that Bounded_String
should be a record containing a character count, plus an array of
characters containing the max size (as opposed to some pointer-ish
implementation). You can make pointers to these things if you want to
-- A.4.4(106) is not restricting the *user* in any way.
If you want unbounded strings (which *are* implemented using pointers),
then look at A.4.5. These are more flexible but less efficient.

If you allow programmers to play with "+" and "=", you'll ... ;-)

Irrelevant. If you want that, use perl (I'm echoing Laurent's earlier
remark). ;-)
