isn't __str__ the protocol for "coerce to string" ?

__index__ is a protocol for "coerce to an integer that can be used as an
index", which is like __fspath__ would be "coerce to a string that can be
used as a path"

the whole point is that __str__ will "work" with virtually anything --
whether it can reasonably be used as a path or not. I'm not sure that's a
problem, but if it is, then that's what this new protocol is trying to
solve, just like __Index__ enforces that only things that are intended to
be used as indexes will work.
