By the way, CPython currently uses statically allocated types for builtin types like str or list. This may have to change to run efficiently multiple subinterepters in parallel: each subinterpeter should have its own heap-allocated type with its own reference counter. Using heap allocated types means that PyUnicode_Check() implementation has to change. It's just another good reason to better hide PyUnicode_Check() implementation right now ;-) Victor _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/EIEBID2VQKZN6Z3XSAS6LMVHKCIOKHAI/ Code of Conduct: http://python.org/psf/codeofconduct/
