Hilmar,

I try to follow this design principal with the exception of parameter checking at the beginning of a function/method. If something is missing or wrong, then I usually bail out. This generally happens before any environment settings have been made and therefore doesn't require special cleanup.

>I read somewhere that a function (or method) should have a single point of exit (RETURN). Is this considered a general design principle, that should usually be followed?
