Yes; this doesn't change, really. Methods would still need to be invoked
separately, but the query string doesn't need to be passed in; it's part of
the data object.

If it were a property, yes, but I think a method on the result object makes
more sense because we don't want to assume values for these arguments.

That's what I was thinking. Just add something like this to BaseResult
(untested):
def parsedQuery(self, keep_blank_values=False, strict_parsing=False):
return parse_qs(
self.query,
keep_blank_values=keep_blank_values,
strict_parsing=strict_parsing)
def parsedQueryList(self, keep_blank_values=False, strict_parsing=False):
return parse_qsl(
self.query,
keep_blank_values=keep_blank_values,
strict_parsing=strict_parsing)
Whether there's a real win with this is unclear. I generally prefer having an
object that represents the URL and lets me get what I want from it, rather
than having to pass the bits around to separate parsing functions. The
result objects were added in 2.5, though, and I've no real idea how widely
they've been adopted.
