While discussing what to post as an April Fool's joke yesterday, we had a couple of other ideas, listed below. Most of them were rejected because they are too incredible, others because they are too close to our wish list.
- quantum computer backend
- Perl6 interpreter in RPython
- Ruby backend to allow run "python on rails"
- mandatory static typing at app-level, because it's the only way to increase performances
- rewrite PyPy in Haskell, because we discovered that dynamic typing is just not suitable for a project of this size
- a C front-end, so that we can interpret the C source of Python C extensions and JIT it. This would work by writing an interpreter for LLVM bytecode in RPython.
- an elisp backend
- a TeX backend (use PyPy for your advanced typesetting needs)
- an SQL JIT backend, pushing remote procedures into the DB engine
