Summary

Implementation for one of the rules in #1348
Refurb only deals only with classes with a single base, however the rule is valid for any base.
(str, Enum is common prior to StrEnum)

Test Plan

Thanks! I made a couple of minor changes:

  • Moved the utilities below the rule logic function; we do this for all rules
  • Avoid the eager .to_string call for user_symbol method and only allocate it when creating the Diagnostic

Looking at the ecosystem changes, we might want to special case (str, Enum).

Refurb only deals only with classes with a single base, however the rule is valid for any base.

Sorry, I missed this earlier but can you expand on why do we want to diverge from this behavior.

Edit: I think we should keep the same behavior as refurb and check only when there's one base class.

Fair point. After looking at the ecosystem results, I think we indeed should stick with refurb's behaviour (at least until type inference is available).

Only considering classes with a single base is the least error prone.

It also has some false negatives which can be detected by considering multiple bases, e.g. https://github.com/bokeh/bokeh/blob/829b2a75c402d0d0abd7e37ff201fbdfd949d857/src/bokeh/core/property/wrappers.py#L306.

However there are false positives for:

I think the listed limitations are a good trade-off.
