I tend to call them index. If the loop is nested I grab functions to call inner bits. i and j especially can get crazy muddled coexisting (could you even pick two more similar letters? Capital I and l depending on the font maybe?). In general, much prefer languages where I don't ever have to index. E.g. list comprehensions are much more expressive
