But there was evidence. An irrational desire to use an entirely
inappropriate programming idiom to solve a problem. That's a very
common sign that the question is a homework, as some teacher has
come up with a challenge to test her students on the use of
the current topic, whether its suitable in the real world or
not....

List comprehensions are deceptively concise, but in this case
it would result in extra memory usage and probably slower
performance than the simpler in-place solution.  Shorter code
is not necessarily the best code.
