RPython was tried in a production environment some years ago and while it
produced some very nice results, it was quite difficult to work with. Dealing
with those difficulties requires a group of people who are willing to build
RPython code for general applications, run the code and identify what the
difficulties actually are. Then they need to come up with strategies for how
to remedy the problems and implement them in code. This is a very large
undertaking for which Pypy does not have the manpower.. It also reqires people
who are interested in building support for compiled programming languages.
Pypy is a volunteer effort and the only person who was interested in this has
retired from the project.
This makes sense.
But wouldn't the answer to this problem be to invite people like the
Shedskin/Cython developers to join forces with PyPy?
So that they can pursue the general RPython usecase you mention above while the
others focus on JIT and stuff on a common code base?
Wouldn't that be a win-win for everybody?
This collaboration feels so obvious to me, that I am confused why it isn't to
Considering that Shedskin's goals feel almost like a strict subset of PyPy.
