__init__ is a function, taking a default value of [], which is a list,
which is a mutable object. That said, you should remember that this means
that such default value is 'shared' between all instances. If you don't
want that, do something like:

def __init__(self, defaultvalue=None):
	if defaultvalue is None:
		defaultvalue=[]
