As the one who wrote the code, I can guarantee you that the StopIteration value
is not always None.
But I understand your point that for most other users it is always None, and
therefore having special syntax might be misleading

Ok, will do, but what is the bar for a feature to need to go to the mailing
lists first? I thought as this was a relatively minor one it wouldn't need to.
Is it just because it's an actual syn
New submission from Patrick Reader :
I would like to be able to use a `yield from` expression in a `return`
statement without parentheses, as a small quality of life tweak, i.e.:
return yield from gen
instead of
return (yield from gen)
I think this makes sense, since `yield from
New submission from Patrick Reader :
The following code gives a SyntaxError in 3.10, but used to work fine before (I
have tested it in 2.7, 3.8, 3.9):
1not in [2, 3]
It seems to be only the `not in` syntax which is affected; all other keywords
still work correctly:
1in [2, 3

Currently the documentation for the generic forms (e.g. what the parameters in
square brackets mean) of standard collections (e.g. collections.abc.Generator),
is still on the typing page

Per bpo-41263, code.__new__ now uses Argument Clinic. However, it still has a /
marker which prevents the use of keyword arguments

Similarly, when passing a subclass of dict to exec or eval as the locals or

New submission from Patrick Reader :
When a frame's __builtins__ is a subclass of dict with an overridden
__getitem__ method, this overriden method is not used by the IMPORT_NAME
instruction to lookup __import__ in the dictionary; it uses the lookup function
of normal dictionaries

I would like to note that syntax like this is in heavy use in the Code Golf
community (a sport in which the aim is to write the shortest code possible to
complete a particular task).
It will be disappointing if it becomes an error and break many past

It would be nice to have a `.path` method or property on
`tempfile.NamedTemporaryFile`, `tempfile.TemporaryDirectory` which produces a
`pathlib.Path` of their `.name` attribute, so one can use the modern interface
directly.
I think a method would be more
