So, it is with confidence in Python's future that I give the floor to Mark Lutz. Excellent job, Mark. And to finish with my favorite Monty Python quote: Take it away, Eric, the orchestra leader!

The new Windows import rules are simpler than before: If the PYTHONCASEOK environment variable exists, same as before: silently accept the first case-insensitive match of any kind; raise ImportError if none found. Else search sys.path for the first case-sensitive match; raise ImportError if none...
