Hmm... sounds a little bit heavyweight for a config file reader/writer.

You can actually already do this by reading the config file in with 
``list_values`` set to ``False``. (This stops the parsing of values - 
except to remove any comment and handle multi line values I think). You 
then use the ``walk`` method and pass in a callable which is called on 
every value and each value is substituted with the return. Properly 
handling lists would be a pain this way - you would want to leverage the 
code already in ConfigObj to do this.

This however this isn't symmetric with ``write`` which *currently* won't 
quote a value if it doesn't need it - so a string value of  '1' will be 
written without quotes.

Do you envisage needing programmatic writing from Turbogears ? If not, 
ConfigObj can possibly already do what you want.

I'm happy to implement ``unrepr`` mode *anyway*.

All the best,
