Clojure makes default choices "easy", and non default choices "harder" for a reason: to guide people. It's like the mantra "if you find it hard to write, you may be doing it wrong (though it's still possible to do)". Also, for the REPL, there will still be the (use 'clojure.tests) call that you can use in your REPL bootstrapping code. > To me, the discussion seems to be confused; I understand why making an > implementation simpler is important.

I don't think I'm confused, AFAIC: I'm not even thinking from the implementation perspective, but from the consumer perspective. It's also psychological: if you remove :use, even at the cost of keeping :refer :all, that's one less top-level 'ns directive to remember. I agree that it is micro-optimization, but this counts too, noticeably because it's one of the first things a newcomer is confronted to when he starts seriously with the language. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
