to explain this point I'm going to use a hypothetical language called Blub. Blub falls right in the middle of the abstractness continuum. [...]
As long as our hypothetical Blub programmer is looking down the power continuum, he knows he's looking down. Languages less powerful than Blub are obviously less powerful, because they're missing some feature he's used to. But when our hypothetical Blub programmer looks in the other direction, up the power continuum, he doesn't realize he's looking up. What he sees are merely weird languages. He probably considers them about equivalent in power to Blub, but with all this other hairy stuff thrown in as well. Blub is good enough for him, because he thinks in Blub.He is, of course, completely correct, as he is every time he writes about general things. The power of his mind to grasp truly general concepts and put them in simple words is astonishing. But now look at this (from Re: Revenge of the Nerds, again emphasis mine):
I know that Python currently imposes these restrictions. What I'm asking is what these restrictions buy you. How does it make Python a better language if you can't change the value of a variable from an outer scope, or put more than one expression in a lambda? What does it buy you to distinguish between expressions and statements?Later, he seems even more desperate:
I'll explain all these things. On this blog, we will first unlearn every wrong concept from thorny history of programming, and then we'll see how programming should be done. In a language whose concepts are powerful enough to confuse even Paul Graham.
