every time I type the above line, I wish Lua had the += operator. It depends on
the kind of program, but in some use cases (e.g. statistically evaluating large
data files) I need to type this kind of line frequently.

yes, interesting idea, but I also think that this would be too magic. I would
prefer simple +=. I know from time to time this comes up in this list but I
never understood why Lua does not have +=.
