Because I find this "performance oriented Clojure" vs Java fits quiet well in the "easy" vs "simple" mindeset.[*]. Adding Java code in a Clojure project is certainly easy if you happen to already know the language, while no amount of prior experience in idiomatic Clojure will help you in writing perfomance oriented Clojure as it can be a completely new idiom. But I do believe that the resulting code (as a whole, not just the small performance critical bit of code) is simpler with two idioms in one language than with two languages.
FWIW, I, for one, am really glad that Clojure allows us to select precisely which nice tools we want (have to) throw away (persistent data structures, dynamic typing, synchronized) when the need arises. Reminds me of the "don't pay for what you don't use" motto of C++ except done right (i.e. the other way around, because you don't want to pay wrt simplicity rather than performance, cf. "premature optimization…") Cheers, Bernard [*] https://www.youtube.com/watch?v=rI8tNMsozo0 -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
