Great plans! Good luck!

I think, it would be more useful to start it as a library compatible
with Ravi, Lua 5.1 (and LuaJIT), 5.2 and 5.3. If you start it as a
part of Ravi, it would need extra work to factor it out. If you start
it as a separate lib, you can then add Ravi-specific optimizations if
it detects Ravi. (By the way, what is the right way to detect Ravi
from Lua?)
