I do understand that. It's just that as PyPy is a relatively complicated
program it follows that rpython is good for making a lot of python
programs amenable to analysis. (Yes as a by-product, but in my opinion an
incredibly powerfull and usefull one)
No. RPython is not good for making a lot of Python programs amenable for
analysis for several reasons. One of them is that although RPython is a
rather nice and powerful language is *is not Python* (although it
deceptively looks like it). That means (as Michael already pointed out)
that it is really hard to convert an existing program to RPython since
the style of programming is just totally different. So all the people
saying "yay, I want RPython to speed up my program" will run into deep
problems, no matter how much the RPython toolchain will be brushed up.
After all, the PyPy standard interpreter was written in RPython from the
ground up.
The other problem is that you have nearly no standard library available
in RPython, which is also something that is not easy to change. And it
is easy to forget just how much most python programs are dependent on
the stdlib :-).
