And that's what happens when you try to contrive an example to support an illogical argument. You end up arguing on the basis of code that no one would write.
In hindsight that was not a very good example!
not denigrated away in appeasement to those who think anything not found in their first programing language is weird or dangerous.
That might be whats happening here - I guess the only way to know would be if I watched myself the next time I use while instead of until and see if I am doing so because its better or because I am more comfortable with it.
