Path class Pre-Pre-PEP
Implementation(s)
Reinhold has modified Jason Orendorff's original path.py to fit discussions in python-dev and comp.lang.python and has placed it in Python CVS under nondist/sandbox/path.
Other implementations to look at include the original, path.py and some things that others have mentioned on c.l.p. and python-dev.
Design Principles
1. A Path should be a drop-in replacement for a str or unicode as much as possible.
2. Properties are the interface for immutable attributes of a Path. For example, a Path's basename will be the same regardless of data on the local filesystem.
3. Methods are the interface for mutable attributes, for example, the last-modified-time.
