Thanks for posting this."

Dear all,

Thanks indeed.

"[. . .]

3. Removing meaningless repetitions contributes to usability. But X := X + Y 
is only one instance where Ada required such repetition. [. . .]

[. . .]"

I wrote a function to increment as a workaround but opinionated Anita 
Enmark did not like it. Engineering and opinions.

"   if X in T'Class then
       declare
          XT : T'Class renames T'Class (X);

T'Class is repeated 3 times."

Sorry: 2 times.

With best regards.
