Not necessarily. In fact, a string.String ABC could have only a single method: .__str__() defined.
That wouldn't be very useful; object.__str__ exists and is functional, so EVERY object would count as a string.
No, only those objects that register with the ABC would be considered string-like, not all objects implementing the .__str__() method. In regular Python, only str() objects would register with strings.String.
Oh, gotcha. In that case, it would still be pretty much the same as the __fspath__ proposal, except that instead of creating a dunder method (to implement a protocol), you register with an ABC. ChrisA
