With 1.2 almost out the door, we should talk a bit about where to go with 1.3. There's always more work to do, but in this case there's a few directions we could probably go.

Some obvious items will continue to see work:

* 1.9 libraries, interp, compiler, parser
* 1.8.6 bugs

But there's others that we may need to prioritize:

* Ruby code execution performance
* Specific library performance (YAML, IO, Java)
* More Java integration refactoring (esp. subclassing)
* "Compiler #2" to produce normal Java classes from Ruby
* Improvements to AOT compilation (all-at-once, eliminate runtime codegen)

And there's a number of internal chores to work on too:

* Start generating most of the call path, to reduce duplicate code
* Specific-arity optimizations for block yield (could be big)
* Compiler cleanup and refactoring
* Modularization of core classes that aren't valid on applet, Android, secured envs, etc; also may allow shipping smaller runtimes
* More startup perf work; I have a few ideas

As always, there's way more work than the few of us committing can do, so I think we need to hear from users what's important. Any of these? Other items?
