leap seconds are applied to days at various times, due to

attribute in the `bpy` module, for which you are creating a `context`
attribute in your module.

Suggest OP create a reproducible case, and paste the code and output
verbatim.

My experience with IntelliJ (related to PyCharm): it scans all source

those (if necessary) or inspects their class bytecode, and so on to

What is the right way to prevent this problem from happening?
Thank you in advance,

P.S. I am running on Linux: ubuntu 18.04 with python 3.6.9, also reproduced

You'll need to tell me at this point.

The generate_a_default_value function was called before the call to
get. It was called so it could produce a value that is actually passed
in as an argument to the get function.

Sorry, actually, if you do not answer yes, will always return None, not
the first answer as I suggested.

It won't return until the inner call to question (and it's not using
the return value on inner call). Eventually, (and not until you answer
yes) it will return the first answer.

Thanks for the comprehensive response, dn!
I guess I'm influenced by data classes here, where the object's
attribute type hints are represented by class variable annotations.

Would this be a reasonably correct way to annotate a property with a
type hint?
>>> class Foo:
... bar: int
... @property
... def bar(self):
... return 1

>>> import typing

{'bar': }
I could also decorate the property method r
Thanks, will bring it to the dev list.

Thanks, Greg. Would it make sense for list's __class_getitem__
(GenericAlias?) to perform similar checking as
typing._SpecialGenericAlias (nparams)?

Is this the correct behavior?
Python 3.9.0 (default, Oct 7 2020, 23:09:01)
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

nse to me in Python 3.9: I can use
the built-in generic alias in list in this manner, apparently
successfully:
>>> list[int, int]
list[int, int]
In fact, it appears I can specify an indeterminate number of types. Can
someone explain what this construct means? I suspect this will fail to

Can you please clarify where/when I should call PyEval_InitThreads()? Is this
in the main python thread before any pthread callbacks are generated? If so,
should this be done only once?

Starting with a proposed language change before you've explored the
existing options isn't likely to be the best approach (and would
likely have meant you could resolve your issue without needing to
bring it to python-ideas at all).
