What about instead of separate files turning the single file into a pseudo-zip file containing all of the proposed files, and provide a simple tool for removing whatever parts you don't want? -- Zach ___ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/

You can do this for yourself by adding the following to sitecustomize.py or similar: import sys def printingbreakpointhook(*args, **kwargs): print(args, kwargs) return sys.__breakpointhook__() sys.breakpointhook = printingbreakpointhook -- Zach ___ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/

I'm not terribly keen on cluttering up C:\Windows with this, but that's a minor issue. -- Zach ___ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/

I am not familiar enough with the threading implementation to be anything more than moral support, but I am in favor of making some change here. This is a significant blocker to Cygwin support, which is actually fairly close to being supportable. -- Zach ___ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
