No, you are forgetting that these operators are intended to
be defined for all sorts of types, where the temporaries may
be very large data structures, such as matrices.

Anyway, I'm not an Ada programmer, so I don't really care if
Ada has these operators or not. If I had to do stuff like this
in Ada, I would just write the appropriate procedures and be
done with it. In C++, I use these operators all the time. I
just did a quick search through the source code we've added to
out trading system and counted around 500 uses of augmented
assignment operators (+=, -=, *=, /=), and yes, we actually do
have a few cases of /=. We also have a few of those complicated
left-hand sides that people talk about; here's one:

     (*fxMap)[exposure.secCurr.id().get_key()] += exposure.secExp;
