For lists, the reason .sort() returns None is because it makes it clear it's a mutation. Returning self would make it look like it was doing a copy. > My pet peeve example: a.reverse() > > I would also like to see simple methods for "+=" operator and such.

I have in mind some sort of code optimizer. It wouldn't be anymore efficient than the other way. For a code optimizer, you'll either have to parse the python code or use special objects (much like numexpr does), and then you might as well use the operators. -- |>|\/|< /--------------------------------------------------------------------------\ |David M.
