He doesn't appear to know the difference between perl and perl6, either - then again, he lumps all the lisps together as well, so maybe he really means "language family" when he says "language".<p>Oh well. All my favourite production tools (perl, C, unix ...) have been declared dead at least once - that's how I know they're well proven and solid. Apparently now three of my favourite language families are also overrun with people thinking about how to implement them - I'm not quite sure why that's a bad thing either.
