The various path-manipulation functions of ``os.path`` [#os-path]_
will be updated to accept path objects. For polymorphic functions that
accept both bytes and strings, they will be updated to simply use
code very much similar to
``path.__fspath__() if hasattr(path, '__fspath__') else path``. This
will allow for their pre-existing type-checking code to continue to
function.
I afraid that this will hit a performance. Some os.path functions are
used in tight loops, they are hard optimized, and adding support of path
protocol can have visible negative effect.
Do you have an example of os.path functions being used in a tight loop?
