But each language encourages a certain style of design and algorithm, so it IS fair to compare the way that the language encourages a certain approach. For example, Clojure encourages you to use a more functional approach and persistent data structures. If this ends up being way slower than the mutable approach that Python encourages, that is worth knowing. I remember one year, my ICFP VM in Python ran ridiculously slow in part because Python doesn't have a switch statement, whereas other languages do. So it is useful to look at what a language does and does not allow you to do, and how that impacts speed. My point is: no comparison is going to be exactly apples to apples, but the comparison can still be useful. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
