[issue31995] Set operations documentation error

2017-11-09 Thread Alexander Mentis 

New submission from Alexander Mentis :

Documentation for set/frozenset says |=, &=, -=, ^= operators do not apply to 
immutable instances of frozenset. This is incorrect. These operators can be 
used on frozenset; however, they behave differently on frozenset than on set. 
When used with set, they modify the target set in place. When used with 
frozenset, they return a new frozenset that replaces the target frozenset.

[issue31995] Set operations documentation error

2017-11-10 Thread Alexander Mentis 

Alexander Mentis  added the comment:

I don't think you understood my bug.

That the augmented assignment operators work differently for set and frozenset 
is not the issue.

The issue is that the documentation says that the |=, &=, -=, ^= operators do 
not apply to immutable instances of frozenset. This is incorrect.
