Deprecation decorators messing with type checking about polars HOT 2 OPEN

In all transparency, this might be purely a PyCharm problem and that there is nothing Polars can do.
But it's an IDE that is used so widely (in particular in the professional world, with PyCharm Professional for Windows) that it's worth investigating IMHO.

I've also raised this issue (and another similar one concerning arithmetic calculations on pl.Series) directly to PyCharm in parallel: https://youtrack.jetbrains.com/issue/PY-73306/Type-hints-fail-for-decorated-functions

from polars.

Hi, just as an update the main issue raised here was a problem with PyCharm, and is solved in their latest build.
The other issue is still present, but I suspect this is also a problem on their end.

series = pl.Series(values=[1, 2, 3])
(series - series.mean()).sum()  # tooltip saying: Unresolved attribute reference 'sum' for class 'Decimal'

I'll try to get to the bottom of this with them and will close this issue myself if and when this is solved by their team.
