I have two problems with JRuby. First and foremost is the complete lack
of an FFI. The whole "Just rewrite it in Java!" mentality that some
people have is simply impractical. Second, the spec is nowhere near as
complete as they would have you think.
Check out my personal test suite:
cvs -d :pserver:anonymous at rubyforge.org:/var/cvs/shards login
cvs -d :pserver:anonymous at rubyforge.org:/var/cvs/shards checkout ruby_test
Then try running JRuby against it. And then consider that I've
explicitly commented out some tests for JRuby because it doesn't support
certain methods. Like most of the Process module functions, for example.

I really, really, really wish Evan hadn't gone this route. Sydney was so
promising, and actually had some cool new features. I don't see any
practical advantage to targeting a two year old spec. Nor do I see
Windows support materializing in the next year. Or two.

Yeah, I actually considered applying for a position working with John at
one point, but I just can't bring myself to work for Microsoft. I have
considered applying for 501(3)(C) status for the Win32Utils project, and
seeing if Microsoft would contribute.

I'm really not too happy with what I'm hearing about 1.9. So, we've
added a VM, and a GIL. And a bunch of highly dubious methods to the core
classes. I just don't see the ROI, especially when I think we simply
could have made some really good improvements in the 1.8.6 branch.
Anyone remember Eric Mahurin's array.c patch? I still want to get that
into the 1.8.x branch.
And I've seen some interesting work on the garbage collector:

I'd like Wuby to be more than packaging, though. I'd like complete
rewrites of some of the core classes.
Any, thanks for your input Patrick. Much appreciated.
