Thanks for checking, Alexander. I have created ticket CLJ-1277 with a patch that improves the performance of the case you found, as well as for java.sql.Timestamp printing that also had reflection in it nearly identical to what you found. http://dev.clojure.org/jira/browse/CLJ-1277 Feel free

Good point Timothy - 100% agreed on the value of hard facts / benchmarks. Though I think it's still useful to have some discussions first, in order to determine where to start / what to benchmark / where the problems are likely to be hiding. Good research should start with an understanding of t

One of the problems with these sort of discussions is the total lack of hard facts.

That's what I said earlier, I need to find some type to dive into it. As far as Scala is concerned, it's not on my list of items to learn. Too Java-ish to me and clunky. It's not because you mix all the latest features in a single language that the result is a significant landmark. It took a sign
