Dynamic Language Support on the JVM

"We noticed over the last couple of years that the Java developer community — unlike the .NET developer community — was starting to experiment with dynamic languages."

What? He must have missed IronPython and IronRuby. IronPython's performance has been far superior to Jython primarily because of the dynamic language support in CLR. Unfortunately, MS seems to have abandoned these efforts.

Written in 2006.

IronPython was quite young at the time (1.0 only made it out in November of that year). As far as I can remember, IronRuby didn't even exist at the time, and the CLR had no dynamic language support.

So he's probably correct in that the .NET developer community hadn't yet significantly embraced dynamic languages on the platform.

From 2006... have things changed since then? I hope so, but I don't think so...

They plan to get it into Java 7.

Which will be released roughly 6 YEARS after Java 6. The JVM is an excellent platform but any hope Java (the language) had of remaining even remotely modern died before Sun did. So sad...
