Which is why a former co-worker of mine [occasional seen here]
made a practice of always writing comparisons as "if (0 == a) ..."
so that just in case he typo'd and dropped one of the "=" the
compiler would complain at him. It looked a bit odd the first
couple of times I saw it, but eventually I started using it in
my own code too.
