The reason I was given (which I promptly ignored, of course) is that
it's "best practice" to only have one exit point for a block of code.
Only one way of terminating your loop, only one "return" per function,
never use exceptions, etc. I think it originally came about as a way
to make sure that your clean-up code was called (and to make it easier
for code reviewers to make sure your clean up code was called) and
then started being passed around as a rule among programming teachers
who didn't have any experience outside the classroom.
