If have a file:
import pyximport
pyximport.install(pyimport=True, build_dir='xx')

import six
Since six is a pure python module, looks like cython can cythonize it totally, but I got an error while run this file:
Traceback (most recent call last):
  File "a.py", line 4, in <module>
    import six
  File "/Users/anlong/Library/Python/2.7/lib/python/site-packages/pyximport/pyximport.py", line 419, in load_module
    return load_module(fullname, source_path, so_path=so_path, is_package=is_package)
  File "/Users/anlong/Library/Python/2.7/lib/python/site-packages/pyximport/pyximport.py", line 233, in load_module
    exec("raise exc, None, tb", {'exc': exc, 'tb': tb})
  File "/Users/anlong/Library/Python/2.7/lib/python/site-packages/pyximport/pyximport.py", line 216, in load_module
    mod = imp.load_dynamic(name, so_path)
  File "six.py", line 805, in init six
    _add_doc(reraise, """Reraise an exception.""")
ImportError: Building module six failed: ["NameError: name 'reraise' is not defined\n"]
A quick dig is that reraise is defined with exec statement with reraise function as a string, so seems cython don't support this use case.

Another try is just change the import six to import requests, with another error:
Traceback (most recent call last):
  File "a.py", line 4, in <module>
    import requests
  File "/Users/anlong/Library/Python/2.7/lib/python/site-packages/pyximport/pyximport.py", line 419, in load_module

Another try is with flask and jedi, and they all failed.

Looks like cython have more limitations than the documents said. Improve the compatibility of cython is good, but I don't know how long the gaps were.

Interesting! A bit disappointing, but good to know

FYI, another cython like tools is nuitka, and looks like it can compile more modules to binary.

Might be interesting to read, Guido Van Rossum was rather harsh about nuitka - https://www.pycon.it/conference/talks/nuitka-the-python-compiler

Hey all, I wrote up a blog post giving some motivation for the new direction we're thinking of taking for Pyston v2, check it out!

@kmod What happened to dpro?

Any new developments in the reboot?

We're hoping to do our first release next week!
Key word is "hope", it's been a week away for a little bit now :)

Hi folks, sorry for not logging into gitter for a very long time :/.

https://developers.redhat.com/blog/2020/01/20/mir-a-lightweight-jit-compiler-project/

I did notice that project too. Sounds interesting. Currently it says: This code is in initial stages of development. It is present only for familiarization with the project.
Looking forward to see what they come up with. Having an optimizing JIT which is faster than LLVM would be very nice :)
