hmmm.. well, you can't do it that way ;)

you can write your function such that the order in which the arguments are
processed is static (using kw.items() and a series of if..then statements in
some specific order) in order to get this done, but I don't see the
advantage to 'knowing' the order that the keywords were used by the calling
function.

I have used something like this:

def foo(**kw):
 for k,v in kw.items():
  if k == "bar":
   print "bar keyword value:",v
  elif k == "baz":
   print "baz keyword value:", v
 .
 .
 .


in code that was building arguments to pass to ipchains, and it seems to
work OK. does that help?
