Well I think C++'s += is ugly in the first place :-)

No you cannot always do a reciprical without running into rounding
problems. Consider reduction of a matrix.

How many programmers do you think that wouldn't do:

   A /= B;

and then when the compiler complains they tear their hair out saying why
why why?

   or they are trying to reuse some old code:

      if A /= B then

   and say "Hey! There is bug here."
