I’m one of those weirdos who can inline a double negative instantly so, I didn’t read it yet but I probably will because I’m curious about the title anyway

Oh my dear lord I didn’t think I’d actually disagree with the f’ing article but I had like 8 cases today that made me wish I had a built in if-not keyword! I mean, every language with the billion dollar mistake probably needs a language feature designed to pay back some of that.

I think the author would probably be fine with an if-not. It doesn't hide the double negation like unless.

Are you saying you don’t want to have to apply De Morgan's Theorem any time you read a headline?

So you’d be in favor of dropping “unless” from the English language because it was misused in that title? :)
