[pypy-dev] External RPython mailing list

[Leonardo Santagada]

If anyone wants to pay developers to work on rpython it should
probably follow this wishlist and not focus on trying to merge
shedskin into pypy (for the all the reasons given above).

Here is my version of the list

Yes, this should be the highest priority. I could add documentation,
doctests explaining stuff, templates for new modules and other things,
better error messages.

did anyone ever really needed this? Would be cool I think, but unnecessary.

also I don't know about the utility of this for rpython itself, would
be interesting if there was a jit backend that used llvm to better jit
everything.

both are nice to have in a language with type inferences. Without this
explicit in the code maybe the error messages would be even more
complex to deal with.

could be @specilize.argtype(42)

I would add:
        . tool to automatically generate stubs for c libraries
        . c++ support (to be able to use c++ libs directly on rpython)
        . better java support (because the jvm matters).
        . better tooling (profiling, debugging etc)
        . separate compilation and/or some cache to speed up compilation.
