I wonder if this would work for python.
CPython merged[0] an experimental JIT compiler into mainline based on the author's previous paper, Copy-and-Patch
The Faster CPython team at least is aware of the paper and probably will look into it
do you mean more specifically than the generally similar approach that worked for https://pypy.org ?
~~It didn't work; PyPy moved away from partial evaluation years ago~~
Sorry, I think I was responding to completely the wrong comment. I would also like a more general-purpose tool for writing fast programming language implementations
