@mhvk @eteq. I'm just seeing this issue for the first time (mentioned in https://github.com/astropy/astropy-project/pull/283). Proposal https://github.com/astropy/astropy-project/pull/269 will outline similar ideas. Nice to see convergent evolution!

In mathematical contexts ``inf` is a relatively common default: - specifying the norm, e.g. L-infinity - domains and ranges So a `Literal[inf]` would be very useful in those contexts.

This would really only be practical if the enums were "batteries included" in base python. Having every library define their own Enum and then, for correct type checking, require users...
