Personally, I agree with you - I was merely explaining *what* the idiom was
to someone who doesn't know.

I go well out of my way to avoid this idiom, as I feel you should always
have the termination condition at one end of the loop, preferably the top
(except in *Exception*al circumstances). For this reason, I would usually
use a Stream heirarchy of classes for handling files.
