Scala 2.7.4-rc1 has been released. It incorporates a few important fixes related to serialization of anonymous functions and generation of Java generics, but the big change is the improved Scala plugin Scala IDE for Eclipse. This means that my backport is now obsolete.
The announcement contains all the juicy information.

That backport was great work Ismael. Many thanks from me, and I’m sure from all the people who’ve been using it while wait for 2.7.4!
Thanks, Miles. All made possible by your work, of course. Happy to see an official release with it. :)
Best,
Ismael
Ismael,
I was indeed very valuable to me.
I would have had to give up on introducing a bit of scala in my projects without it.
Glad to be of help David. :)
What has been your experience with Scala in your projects so far?
Ismael
It depends on the perspective.
The scala code itself, though the plugin gave me an hard time, was still a joy to write.
The real issue lies with java code using the scala code (ie more than 99% of our codebase).
For my team to discover and use any code I can write in scala, I really need autocompletion to work flawlessly.
That point is totally blocking.
After that, there are silent failures like the various refactoring not even noticing they should affect scala code.
David
I agree.
We’re using Scala more these days and there are quite a few annoyances in terms of tooling and interoperability with Java.
Thinks are improving though and 2.8.0 looks very promising, so I think it’s a good choice in the long run.
