I could not have hoped to see a more perfect example of the Blub effect in action if I had invented it myself. 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. http://www.paulgraham.com/avg.html > It seems to me the equivalent of an advanced driving course teaching you > how to customise your car rather than involving any actual driving. You don't think that adding a cache for an expensive function is programming? If you had ten expensive functions, and you wanted to add a cache to each of them, would you write out ten separate caches (probably copying and pasting the code each time)? Or would you write a function that builds a cache and adds it to the expensive function *once*, then call it ten times, once for each function being wrapped? My examples didn't include a full-blown cache, just the beginnings of one, but the principle still stands. Program smart, not hard: don't do things by hand if you can write a function to do them. That you think that this is not programming is an indictment off your programming skills. These sorts of functional programming techniques go back to the 1950s, Lisp is literally the second oldest high-level language ever (only Fortran is older). You may or may not have been a hotshot in your little corner of the programming world, but there's an entire world out there. -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
