stijn	40ad8f1666	all: Rename "sys" module to "usys". ... This is consistent with the other 'micro' modules and allows implementing additional features in Python via e.g. micropython-lib's sys. Note this is a breaking change (not backwards compatible) for ports which do not enable weak links, as "import sys" must now be replaced with "import usys".	2020-09-04 00:10:24 +10:00
Jonathan Hogg	37e1b5c891	py/compile: Don't await __aiter__ special method in async-for. ... MicroPython's original implementation of __aiter__ was correct for an earlier (provisional) version of PEP492 (CPython 3.5), where __aiter__ was an async-def function. But that changed in the final version of PEP492 (in CPython 3.5.2) where the function was changed to a normal one. See https://www.python.org/dev/peps/pep-0492/#why-aiter-does-not-return-an-awaitable See also the note at the end of this subsection in the docs: https://docs.python.org/3.5/reference/datamodel.html#asynchronous-iterators And for completeness the BPO: https://bugs.python.org/issue27243 To be consistent with the Python spec as it stands today (and now that PEP492 is final) this commit changes MicroPython's behaviour to match CPython: __aiter__ should return an async-iterable object, but is not itself awaitable. The relevant tests are updated to match. See #6267.	2020-07-25 00:58:18 +10:00
