Re: triple negation - an idiom?

Update: clarified for boolean...

Considering the previous responses, I'll throw my 2p in.

I prefer the named operators, such as not to !, because they don't disappear as easily into the punctuation forest that Perl sometimes turns into.

(Which makes me think that not not would be the named unary positive operator for booleans, just like + is the positive sign operator. Maybe a nice alias like aye instead?)

No, not not can't be used as a non-punctuation equivalent to the unary +.

not not 2 is equal to 1.

Yes, agreed. I was thinking of Booleans, where it's not an issue. Though my telepathy is in the shop this week.
