+1 from me, with the following suggestion: it's probably worth adding the
to doco that people working with dict-style query_string params should
probably go make a dict or OrderedDict and use:
just to make the other use case obvious.
An alternative would be to have add_ and append_ methods with set and
list behaviour. Feels a little like API bloat, though the convenience
function can be nice.
