[New-bugs-announce] [issue13672] Add co_qualname attribute in code objects

[Arfrever Frehtes Taifersar Arahesis]

New submission from Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA at GMail.Com>:

PEP 3155 added qualified name as __qualname__ attribute in classes and functions. It would be useful if qualified name was also available as co_qualname attribute of code objects.

>>> import sys
>>> class A:
...     def f1():
...         return B.f2()
... 
>>> class B:
...     def f2():
...         return sys._getframe(1)
...
>>> A.f1.__name__
'f1'
>>> A.f1.__qualname__
'A.f1'
>>> B.f2.__name__
'f2'
>>> B.f2.__qualname__
'B.f2'
>>> frame = A.f1()
>>> frame
<frame object at 0x7f9c1adca3a0>
>>> frame.f_code
<code object f1 at 0x7f9c1ae4be40, file "<stdin>", line 2>
>>> frame.f_code.co_name
'f1'
>>> frame.f_code.co_qualname
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'code' object has no attribute 'co_qualname'


Suggested behavior:
>>> frame.f_code.co_qualname
'A.f1'
