Using x as the loop iterator instead of i

@zlice I guess it is more clear to have an index called i, than x. At least when it is not a 2D loop or something. However, x is not too bad of a name, anyway, although the best would be to name it even better than i or x...

Invective! Verb your expletive nouns!

Actually, the i-n thing is cause of FORTRAN (I-N in FORTRAN are integers; all other chars are floating point), and the standard of maths. It's not a bad habit at all in any newer language, and you're fine as is
