The RPython toolchain has another mode of operation, which outputs higher-level class-based code rather than low-level C-style code. They use this for a CLR backend, but it would be interesting to try implementing a JavaScript backend at that level and compare it to the lowlevel+emscripten approach.

(This may have been tried in the past; in the post "10 years of PyPy" it's mentioned that there was once a JavaScript backend but it was removed because it was a horrible idea: http://morepypy.blogspot.com.au/2013/02/10-years-of-pypy.htm...)

Common Language Runtime? I can't find any mention of this backend.

I got my acronyms wrong, it's called the "CLI" backend, but it's definitely in there: http://doc.pypy.org/en/latest/cli-backend.html

Heh, actually it might be possible to cheat a little with this backend as well, using http://www.jsil.org/ to translate the output of the cli backend into javascript. Trying C+Emscripten versus CIL+JSIL would be a very interesting comparison.
