New submission from João Bernardo <jbv...@gmail.com>:
I just realized the builtin function `vars` can't handle custom objects without
the __dict__ attribute.
It would be nice if it worked with objects that have __slots__ to make them
look more like normal objects and to make debugging easier.
I changed the source of "Python/bltinmodule.c" to accept this new case, but, as
I'm fairly new to the C API, it may not be much good.
I'm attaching the whole file to this Issue and the `builtin_vars` function was
modified (lines 1859 to 1921) to work with:
__slots__ = ('a', 'b', 'c')
__slots__ = 'single_name'
__slots__ = {'some': 'mapping'}
The output is a dict (just like in the __dict__ case).
#Example
>>> class C:
__slots__ = ['x', 'y']
>>> c = C()
>>> c.x = 123
>>> vars(c)
{'x': 123}
