It's strange that many programmers in this topic feel that multiple return points are bad. It is very clear how nesting makes code logic more complex, but why many return points are a problem at all? They don't require you to do extra work while reading or writing the code, actually it is exactly the reverse IMHO, every return point remove some possible future state.

Also many times early return is an exact translation of the way we think in our natural languages: "if that is this way don't continue at all", "if this precondition is meet return that value", and so forth.
