Well there are discussions in criss cross here :-) Some want += for
speed-up reasons, some want it for readability and some want a thing
like idem to have the compiler unroll complicated functions if I
understand correctly.

At any rate I wouldn't mind seing Age'Inc (1); in addition to idem as it
would help those who have complicated expressions they only need to
increase by some number.
