dependency on past generates warnings in Python 3 #145
Description
uncertainties imports imp via past at import time, but imp is deprecated from the standard library, which means that in the current state, uncertainties will not be compatible with Python 3.12
This is a problem for me as I want to future-proof a package I'm maintaining which depends on uncertainties, so I'd like to treat deprecation warnings as errors, and don't want to ignore the ones coming from uncertainties.
I believe the patch is trivial so I'll give it a go but I wanted to open an issue first for reference.
reproduction:
# t.py
import uncertaintiesand running on the command line
python3 -Werror t.pyyields
