some might argue this is an ancient carryover, without clear value. I
can certainly envision usage of other letters whenever this helps
clarity in some way. I could imagine using something else temporarily
(at least) while I work on some section of the code so I could easily
come back to it.
I wonder if the first programmer to use i as an index ever considered
the legacy he was creating?
