Need extra () around a or no?
sizeof((a)) / sizeof(((a))[0])) ?
Hm, good question. I guess not, I've seen many projects use this macro without that many braces, but maybe they're all wrong ;-)
As long as 'a' is a simple array all should be fine, I guess. Using ARRAY_SIZE on something other than an array is probably a bug anyway.
