ok. i found a nice workaround (if one dare call it that:-)

class dictlookup(type({})):
    def __getattr__(self, name):
        return self[name]

then i can do:

def func(...,somedict,...):
    m = dictlookup(somedict)
    ...
       m.key1 
    ...

which is reasonably short and additionally seems more robust.
I think it's generally quite nice for dictionaries containing 
'strings' as keys which you know in advance and want to access
without noise.
