Might want to catch AttributeError in this routine - not all func
arguments will have a func_code attribute. See below:
class Z(object):
def __call__(*args):
for i in range(3):
yield 1
for i in Z()():
print i
# prints 1 three times
import types
print type(Z()()) == types.GeneratorType
# prints 'True'
print Z()().func_code
# raises AttributeError, doesn't have a func_code attribute
