by regular expression do you mean a string that is interpreted as a regular expression or a compiled regular expression object?
to avoid confusion, if the former then no doc change probably needed, if the later the type hints in the signature would also need to be updated and some code changes required?

I think he meant a compiled regular expression, this is how we are trying to type it in the stubs.
I believe we should align all the docs, since it uses the functions of re under the hood the functions below support re.Pattern so compiled regular expression is also accepted at runtime.
If we look at the docs it seems like it is a bit unclear what regular expression means because I would assume it is just a regular string in the for r"...".
So the question is should we allow for compiled regular expression as it is supported at runtime?
