Speaking as somebody who regularly maintains code written two to three
years earlier in a number of projects, I would seriously think of not
reusing "key" and "value" in both loops. As things get more complicated,
and particularly if you use that as a general pattern in your work, you
will go cross-eyed trying to work out if there are scoping (or
accidental variable hiding) problems.
Basically, try to write code so that something that looks wrong *is*
wrong. In this, it looks potentially wrong, but turns out to work. That
kind of slight brain speed-bump won't help you spot real errors quickly
in the future.
