Right (IIRC, I initially used a double underscore as separator), and
that's because in ObjC the method

  [object method:arg1 withSomething:arg2 withSomethingElse:arg3]

is completely unrelated to

  [object method:arg1 withSomethingElse:arg3 withSomething:arg2]

I wish I had a way, at the time (we were in the 1.x era), to use
something like OrderedDict to carry around the kwargs argument of a
function/method, that could let me use a nicer syntax... I did even
cook-up a quick&dirty patch, but being too biased toward the "dirty"
side it did not go too far.

ciao, lele.
