Wow - the Pyjama Project looks very impressive!
Looking forward to trying it out.

Perhaps you've seen this, but I ran across Tomáš Matoušek’s blog this
weekend http://blog.tomasm.net/category/ironruby/ where he describes a
little interactive Ruby shell that works something like:
$ irb.exe repl.rb
rb> class C
rb| def say_hello caller
rb| puts "#{caller} says hello to Ruby"
rb| end
rb| end
=> nil
Now, he switches languages on the fly:
rb> #py
Now, from Python he imports and runs the Ruby class in Python:
py> import C
py> c = C()
py> c.say_hello("Python")
Python says hello to Ruby
I thought I'd try this in the educational DLR editor/shell that we're
developing in C# (at http://pyjamaproject.org/Pyjama ) and it works!
There are still some issues (running Python code in Ruby didn't seem
to work), and you need the latest drop of the DLR (I used 23458):
http://www.codeplex.com/dlr/SourceControl/ListDownloadableCommits.aspx
which isn't stable. But, the proof of concept is fantastic to see
after all of the hard work. Best of all, the same DLLs allow all this
to work on Linux and Mac OSX too, thanks to Mono.
This means that you can write and compile a library *once* in whatever
language you want, use it from other languages, on whatever operating
system you want. Wow.
Thank you to all those that are making this possible! (And more on our
DLR IDE soon...)
