Oh, indeed -- and I might even agree on the non-platform arguments. And I'm not discounting those -- I'm just saying that the JVM (not Java/Scala/Groovy/whatever) argument is overstated :). IMO, as always. Agreed about Rust as well, I think. Java programmers are already used to the verbosity (tongue firmly in cheek ;)). EDIT: Actually, come to think of it... many of the criteria you mentioned would apply to JavaScript developers, wouldn't they?
