Since mid-September, Aida van de Wetering has pushed around 125 commits to the [dev branch](https://github.com/pola-rs/geopolars/commits/dev/). It now looks like a rebuild around a Polars-native geo expression namespace. Highlights so...

I recently attended a local PyDay (a Python community event) in my city, and the auditorium was around 70% full. That might sound pretty good, but I remember attending similar events a few years ago when the auditorium was packed, basically at 100% capacity. I also got the impression that there weren't many young...

Assuming a large project which might have say fifty variables in [Constants.py](http://Constants.py) is there likely to be any runtime overhead in having `from Constants import *` at the beginning of each module? As far as I know this creates entries for each of those variables in the current local namespace. I...
