PR Summary

My latest attempt at making on_demand_imports.py less repetitive and error prone
I expect I'll need to iterate a couple times on this.

Gains:

  • developer experience: far less boilerplate required to add optional dependencies, and an overall lighter module
  • user experience: no more necessary startup overhead for some optional deps (like pandas and requests) who were imported even when not used.

TODO:

  • cleanup history
  • add a couple tests to check that using a missing import raises the expected error (currently I think this is not tested because we skip any test that requires deps that aren't available)
