Bug introduced in 10.0.0. Fixed in 10.4.0
I think I found a bug in KeyIntersection
(Mma 10.2). To illustrate, input the following:
KeyIntersection[{Association[], Association[]}]
This returns KeyIntersection[{<||>, <||>}]
instead of {<||>, <||>}
. Only one of the inputted associations need be empty to create this problem.
Am I right that this is a bug? If so, is it fixed in 10.3?
