AST for enum declarations with multiple names

Hi,

I am parsing python files using your syntax tree. I found a enum declaration where multiple names are assigned to one value in a single line.

from enum import IntEnum

class MyEnum(IntEnum):
  A = B = 1

def MyFunction(param : MyEnum):
  print(repr(param))

In the syntax tree the left expression "A = B" is a TupleExpression. However the items collection is empty, so I have no way to get any of both names.
