Pass attribute names:
>>> def always(name):
... def always(f):
... def wrapper(self, *args, **kw):
... print attrgetter(name)(self)
... return f(self, *args, **kw)
... return wrapper
... return always
...
>>> from operator import attrgetter
>>> class A(object):
... def __init__(self, clk):
... self.clk = clk
... @always("clk.posedge")
... def hello(self):
... print "hello world"
...
>>> class clk:
... posedge = 42
...
>>> A(clk).hello()
42
hello world
There may be better ways depending on your usecase.
