Re^4: Double your return!!!!

It also normalizes undefined values to the false empty string, so that the calling code needn't guard against warnings. I'm not sure if context makes any difference here; I have this feeling it does, but a few very quick tests didn't confirm it.

Makeshifts last the longest.

I was assuming (on the basis of the name and the way it was being used) that $ok in the original example was a boolean value, hence could be returned directly without the need for further cleaning. I did actually think of suggesting `!!$ok` originally, but I remembered the controvercy the idea engendered when I suggested that once before at Re: Re: variable set to 0 ? 0 : 1, so I tried to dodge the issue. However, it seems there is always some jerk ready with the -- marker even when they obviously do not understand the issues at hand. Even asking a question (as at Re: Re^2: Double your return!!!! is enough to get the language lawyers scribbling. It's a real shame they don't have the bottle to expound their opinions with words as well as actions. FWIW, I learned another tid-bit. Thankyou. Examine what is said, not who speaks.
