Return *

Everything in moderation and moderation in everything. And with that in mind: Don’t return from multiple points in a method.

I think this is correct to some extent, but as with most rules, the best coders, IMO, know when to break them. I'd probably re-define this to say "only have well-known and obvious return points".

When tidying up some code that had seriously evolved beyond its original purpose recently, one of the most useful and important things I did was consolidate and audit the return and exit paths, and make them sane and obvious. This really helped the clarity of the code.

Absolutely right Andrew. That is why I said "in moderation." Got to know when to break your own rules.

If you're talking to idiots, use small words. If you're writing for idiots, use simple constructs.
And that's enough about that.
