Numba dev meeting 2021-07-06

Attendees: Siu Kwan Lam, Valentin Haenel, stuart, Graham Markall, Todd A. Anderson, Brandon Willard, Guilherme

NOTE: All communication is subject to the Numba Code of Conduct.

Todd: isinstance support
- probably doable nowadays
- needs stuart's dead-branch-prune
- difficulty: "not a research project"
Graham: make progress on https://github.com/numba/numba/pulls/asodeur
- a few of these PRs are dealing with complicated changes.
Stuart: porting datamodel into debuginfo to improve GDB debug experience
- e.g. print(array) in GDB will show up as a readable struct
Todd: Python 3.10
- pattern-matching case statements
- will need early testing to see how Numba is broken
