I'm afraid all this seems like pedantic nit-picking to me - attacking the letter of what I said rather than what I was trying to say.

However I did want to comment on my favourite line in this: " if you properly learn C++, Haskell and Lisp "

Yes. If you properly learn them I would fully agree.

I have in my time made my living as both a C++ programmer and a Lisp programmer and was pretty good at both - but not even close to having properly learned either.

Learning them properly would be a life times experience and I suspect you would be a pretty decent programmer at the end of it.
