No.

No, but I was surprised to see four lines (which adds 
TODO items to my list, among them, look up the meaning of new
with string literals. Is a pointer to a new string made from
a literal different from another of the same making?)

: (c) What would you think of an implementation that caused this behaviour?

I'd think that it might be correct and that I am wrong.
But I'd try to make sure I am wrong.

: (d) I'd be grateful for a very brief indication of your level and broad
: area(s) of programming experience, in Ada and other languages.

Writing programs for a living mostly in Java (standalone and for Servlet
containers), XSL, Perl; some teaching experience; Ada hobbyist.
