It would be really cool to make Julia self hosting. The easiest non-julia in Base to replace is the parser which currently is in femtolisp. Most of the c++ code is just LLVM which we keep our own copy of because Julia has pretty specific LLVM version requirements that OS provided versions are unlikely to satisfy. Getting the C code out would be interesting since it's difficult to bootstrap a language that doesn't like being ahead of time compiled, but it would be a cool project.
