Confusion about dictionaries - keys use value or identity?

[David Goodger]

Check out http://docstring.sf.net/dps/statemachine.py, a finite state
machine specialized for regular-expression-based text filters. Newest
version (1.2) to be posted soon. I've been using it for my reStructuredText
parser with great success (I'll be posting the parser soon too).
