cgi.py: Ideally, the pseudo-dictionary syntax would go away. It
seems to me that the main reason it is there is to accomodate
form['field'].file syntax. How about the following:
form['field'] = '' #no values for key
form['field'] = 'string' #one value in submission for key
form['field'] = ['string', 'string', ....] #multiple values

Proposed Interface
XXX open issues: naming convention (studlycaps or underline-separated?);
no interface for file uploads yet; need to look at all the various
packages to see if there's anything else missing; need to look at
the cgi.parse*() functions and see if they can be simplified, too.
Parsing functions: carry over most of the parse* functions from cgi.py
