With the release of Java 7 (invokedynamic) the performance of these dynamic languages (like ruby and python) may become much less of a factor (JRuby and Jython). At least that's what the JRuby folks imply: http://www.engineyard.com/blog/2011/jruby-1-6-released-now-w...

Punch Line from Link:

"There’s a very real chance that invokedynamic could improve JRuby performance many times, putting us on par with our statically-typed brothers like Java and Scala. And that means you can write Ruby code without fear. Awesome."

Right on! I was going to make the same comment until I saw yours. Charles Nutter has been very enthusiastic about invokedynamic based speed improvements - can't wait.

A little off topic: as a consultant it seems like the demand for Clojure was been tremendous: Clojure is a nice language and very performant. It will be really interesting to see how much large speed improvements in JRuby will cut into Java's, Clojure's and Scala's developer market-share.

Is there any evidence this is actually true? Currently, IronPython and IronRuby do not have great performance on the CLR despite dynamic support.
