"hard" == "slightly less easy"?
class Spam:
def __init__(self, d):
self.__dict__.update(d)
then
o = Spam(options)
or use the types module (if you have a classic class)
>>> import types
>>> class Spam: pass
...
>>> o = types.InstanceType(Spam, {"x": 5, "y": 10})
>>> o.x
5

My guess is the original intent was to make the command-line
parameters act more like regular variables. They are easier
to type (x.abc vs. x["abc"]) and the syntax coloring is different.
