What would this be used for? Other than Path, what types would be
viable candidates for being "string like"? I can't think of a use case
for this feature.

For that matter, what constitutes a "lossless conversion to str"? If
you mean "doesn't lose information", then integers could easily be
said to have such a conversion - but that doesn't seem right (we don't
want things to start auto-converting numbers to strings).

I'm not sure I understand the point.
