[issue17911] traceback: add a new thin class storing a traceback without storing local variables

[Daniil Bondarev]

Daniil Bondarev added the comment:

As suggested adding patch from http://bugs.python.org/issue2786 which prints qualnames in function call exceptions.

e.g:

>>> class A:
...     def __init__(self):
...         pass
>>> A(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: A.__init__() takes 1 positional argument but 2 were given
