The nearest I got was:
-------------------------
class orientate(object):
seen = defaultdict()
@classmethod
def do(self, piece, two_sided=False):
------------------------
which works but requires a change to the function call interface from
orientate(piece) to orientate.do(piece).
I was hoping that repalcing the above with:
-------------------------
class orientate(object):
seen = defaultdict()
@classmethod
def __call__(self, piece, two_sided=False):
------------------------
would eliminate the need for the 'do' but this gives the error:
builtins.TypeError: orientate() takes no arguments
