When you hesitate, opt for fewer lines. Optimization is for later,
and only where things happen more than a hundred times in a row.

Ugly. It is common to use 'i' as an iterating variable, so it is fine
to reuse it below. (In fact, its first use is what I don't like.) But
using it to temporarily store something specific is... disrecommendable.
