that works...
but where does it say arv[0] is the program name?
it seems to be more of a how C works... would be nice if the doc had some
examples of that.

actually just learned that argv0 is program name.
in that case is that because of a platform difference where in macOS it doesn't
allow for program name to be '' and in linux it does?

the following works in Linux
import os
os.execl('/bin/bash', '')
doesn't in mac:
>>> import os
>>> os.execl('/bin/bash', '')
Traceback (most recent call last):

New submission from Siming Yuan :
Using os.execl you can open a new bash shell (eg, using python to process some
env before opening a new shell.

i just discovered cython v0.28 no longer creates instancemethod, so this bug
should technically no longer show up after upgrading cython.
(related cython bug https://github.com/cython/cython/pull/2105)
so the question remains - is it

having a tough time trying to reproduce this issue in pure python.
any clue as to how to create a __repr__ that's unhashable?
class UnhashableRepr(dict):
__repr__ = _testcapi.instancemethod(dict.__repr__)
doesn't work because that
New submission from Siming Yuan <simin...@gmail.com>:
in Python 3.5 it the pprint.PrettyPrinter mechanism got an overhaul, relying on
PrettyPrinter._dispatch dict-lookup based on obj.__repr__ type.
This breaks any Cythonized 3rd party libraries that used to be pretty-printable

tested again with Python 3.4.8 and the bug is observed. patch & builds fine.
strangely, tested building python 3.6.4 on the same environment without patch,
no issues, even though the ffi.c code is exactly the same.

Hi Eric
I understand where you are coming from, but I disagree with having to raise
this to 3rd party tools.
both wheel/pip makes calls to distutils.util.get_platform(). Fixing it in one
location would fix it across the board.
In addition, taking setuptools

New submission from Siming Yuan:
if you subclass a list, and cast it to tuple, the casting does not iterate
through the list.
(casing to list does)
for example, i needed a WeakList where the list only internally contains
WeakReferences that gets deleted as soon as the object ref count goes
Siming Yuan added the comment:
according to inspect.py line 675 - this is only a best effort.
is this intended?
inspect.py @ 672
if isclass(object):
name = object.__name__
pat = re.compile(r'^(\s*)class\s*' + name + r'\b')
# make some effort to find the best
New submission from Siming Yuan:
if the same class name is used within a module, but defined in different
contexts (either class in class or class in function), inspect.getsourcelines()
on the class object ignores the object context and only returns the first
matched name.
reproduce:
