I guess this message is directed at Kirill Simonov.
PyYAML looks much better for teaching programming than Python's pickle as
the files are much more readable than pickle's text version. However, PyYAML
for Windows will not install for Python 3.1. PyYAML 3.08 is looking for
Python 3.0 and it works fine with that. Python 3.1 includes a number of
useful improvements and the latest version is now 3.1.1.
Kirill, do you have any idea when there will be a PyYAML for Windows which
will work for versions after 3.0?
