I agree a decent pathlib may make many of the low-level filesystem
manipulation modules obsolete - just not necessarily all of them. Until we get
an actual module to experiment with, we won't really know.

I'd suggest something like:
y = Path(x).parent(2) + "lib/"
Where the parent function works like (based on the three-part internal data
approach I posted recently):
def parent(self, generation=1):
return type(self).from_parts(
self.basepath, self.dirparts[:-generation], ())
And path addition is equivalent to:
def __add__(self, other):
if isinstance(other, basestring):
other = Path(other)
if self.nameparts:
raise ValueError("Cannot add to path with non-empty name")
if other.basepath:
raise ValueError("Cannot append non-relative path")
dirparts = self.dirparts + other.dirparts
return type(self).from_parts(
self.basepath, dirparts, other.nameparts)
Anyway, I'll try to find some time to look at this on the Wiki. It'll be
easier to bat code back and forth over there.
Cheers,
Nick.
