There was a problem hiding this comment.
Do we need to use this pattern used in final?
try:
f.__final__ = True
except (AttributeError, TypeError):
# Skip the attribute silently if it is not writable.
# AttributeError happens if the object has __slots__ or a
# read-only property, TypeError if it's a builtin class.
pass
return f

I was more careful there because we added the behavior later after the decorator was already in the wild, and I didn't want to accidentally break something. Here, we're adding a new decorator, so I think it makes sense to start with the simpler behavior and adjust it only if there's an actual need.
Sorry, something went wrong.
