Comment:

 That won't work because path's operator== is not the same as the string's
 operator==, so paths that are equal will hash to different values. I'll
 write a patch when I get the chance. You also shouldn't call `hash_value`
 directly - if at a later date filesystem uses a custom string type, then
 that won't pick up its `hash_value` by ADL.
