Bwah ha ha, see what I did there in the topic? It's a programming-language-nerd pun.
This blog thing deserves some followup. I have abandoned the Noodle effort. It was a terrifically fun project, and I learned a lot about Python internals and about languages in general that I'm not sure I would have been able to learn otherwise. It's just not something that I see going anywhere useful. There are so many exciting and/or interesting developments going on right now with LLVM gaining some traction, PyPy getting momentum, the resurrection of Parrot ("'e's not dead, 'e's pining for the fjords"), Pythonistas and Rubyists actually learning from each other, and so on, that I'm sure any of them have a better chance for making programming life better than Noodle.
S-expressions are still awesome.
