[pypy-issue] [issue1673] Can't copy AST-nodes that have missing fields

[mmaenpaa]

New submission from mmaenpaa <mika.j.maenpaa at iki.fi>:

In Pypy it is not possible to copy ast-nodes that have missing fields or attributes.

For example:

>>>> import ast
>>>> import copy
>>>> n = ast.Num(n=2,lineno=2)
>>>> n2 = copy.deepcopy(n)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "lib-python/2.7/copy.py", line 182, in deepcopy
    rv = reductor(2)
AttributeError: 'Num' object has no attribute 'col_offset'
