In the Python 'with' statement, an 'as' clause can be used to store the value returned by the context manager: class Mgr: def __enter__(self): return "text" def __exit__(self, *args): pass with Mgr() as asd: print(asd) However, kdev-python incorrectly marks 'asd' as having type 'Mgr', when the correct type here should be 'str'. This happens to work for the common pattern of "with open(...) as f:" because file objects return themselves in __enter__, but other context managers don't.
Git commit d619a731dbcdc724630118d521583be41f0cf7d3 by Francis Herne. Committed on 10/10/2018 at 00:01. Pushed by flherne into branch '5.3'. Improve support for 'with' statements. The previous code didn't look at `__enter__()`, and assumed that all context-managers returned their own type. We also didn't account for targets other than simple names, e.g. `with Mgr() as (foo, bar):` Thanks to Nicolás Alvarez.
