[Python-Dev] inplace operators and setitem (original) (raw)

Hi,

a general question. Consider:

class A(list): def setitem(self, index, item): # do something with index and item return list.setitem(self, index, item)

lst = A([1,set()])

lst[0] |= 1

lst[1] |= set([1])

Do we want lst.setitem to be called in the second inplace assignment?

A case where this matters is here: http://python.org/sf/1306777
