Can you be a bit more descriptive?

Who reviews the machine code from gcc?
I would love to see the option to write the lower levels in something
other than C, but obviously any choice would have to be a good one.
Otherwise, we end up stuck or with lots of different languages all
being used and making understanding the full codebase harder. For
example, I've wondered if RPython would ever reach the point it could
be considered in the same way, but I don't think it would be wise to
consider both. So, the question I see isn't if Cython should be
allowed for standard library modules, but if the landscape of such
solutions is at a point that any of them is ready to be committed to.
Read my blog! I depend on your acceptance of my opinion! I am interesting!
