Of course - depends on the component we are talking about. There is a
new compiler that is largely being written from the ground up, but
even there the lexer is pretty much a hacked version from Lua, and
there are other bits and pieces that are borrowed too.

Fortunately MIR provides a C front-end, so you can feed in C code and
let MIR convert it. I like this because:

a) Much less effort to maintain it. I had written up the LLVM backend
by hand, using the LLVM api, and it made it very difficult to maintain
and change it. (So I am glad to see the end of the LLVM backend!)

b) It is relatively straight-forward to also support AOT compilation
when you have C output.
