I'd rather like to see an ordered dict like object returned by urlparse
for parameters this would make extra methods superfluous.
Also note that you might need to specify the encoding
of the data somewhere (most of the times its utf-8 but it depends on the
encoding used in the form page).
A nice add-on would actually be a template form object which holds all
the expected items and their type (and if optional or not) with little
wrappers for common types (int, float, string, list, ...) which
generate nice execeptions when used somewhere and not filled/no default
or actually wrong data for a type.
Otoh, this might get a bit too much in direction of a web app framework.
