The copy module will not properly copy/deepcopy weakrefs, it will bomb out with __new__ not having enough args. This is a problem b/c it makes deepcopying of objects that make use of Weak(Key\|Value)Dictionaries difficult. To replicate: import copy, weakref class Test(object): pass t = Test() wr = weakref.ref(t) wr_new = copy.copy(wr)
