[issue36085] Enable better DLL resolution

[David Miguel Susano Pinto]

David Miguel Susano Pinto  added the comment:

I have just found out that commit 2438cdf0e93 which added the winmode argument 
and the documentation for it disagree. Documentation states that default is 
zero while the real default in code is None.

I have opened PR 19167 on github to address it

[issue35338] set union/intersection/difference could accept zero arguments

[David Miguel Susano Pinto]

New submission from David Miguel Susano Pinto :

set union, intersection, difference methods accept any non-zero number of sets 
and return a new set instance, like so:

>>> a = set([1, 2])
>>> b = set([1, 3])
>>> c = set([3, 5])
>>> set.union(a, b, c)
{1, 2, 3, 5}

even if it's only one argument:

>>> set.union(a)
{1, 2}

I think it would be nice if zero arguments were not an error:

>>> set.union()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: descriptor 'union' of 'set' object needs an argument

This would allow to handle any sequence of sets which otherwise requires this:

if len(sequence):
return set.union(*sequence)
else:
return set()
