[pypy-dev] Feedback on Graduate School Research Idea Using Pypy

[yun bao]

I took a look at PyPyJS.  I also spoke with some folks at Mozilla, and have
become very interested in WebAssembly.  I think having WebAssembly as a
target for RPython would be very useful.  Based on what I've learned
recently, it should be possible to write an interpreter in RPython,
translate it to C, then use Emscripten to compile that to WebAssembly.
However, if there was a WebAssembly backend for RPython, it would be
possible to build interpreters than run directly in the
browser (potentially even PyPy.).  That seems like an avenue worth
investigating, doesn't it?  I think while doing that, it would be worth
getting RPython compatible with Python 3.  By the way, these are things I'm
thinking about doing myself, not recommendations to any of you.  I'm still
working on a solid thesis idea for my Master's.
