What do you mean by "all remaining 8 days?". As for feasibility, I think=20 the most difficult part would be to handle Ruby's blocks.

I am not involved in this, so I can't give you a definitive answer, but=20 I think it would be good to try out whether/how Ruby can be sped up by=20 JIT compilation. Maybe the goal of the project should just be to=20 implement some JIT compilation; whether this is done from YARV to e.g.=20 LLVM, or from Ruby directly to something like LuaJIT, or from YARV to=20 LuaJIT, could be an implementation decision by the student (together=20 with the mentor).
