Subject: [ruby-core:56338] [CommonRuby - Feature #8723] Array.any? predicate returns true for empty array.


Issue #8723 has been updated by nurettin (Nurettin Onur TUGCU).


Yes, I meant for .all? (wasn't able to edit) and the behavior is correct according to docs, and incorrect according to my interpretation of sets. (can a predicate be true when you have empty set?)

Are all your children redheaded?
Would this be true if you have no children?
I have no children, therefore none of my children are redheaded.
Therefore 
[].any?{ true } == true makes no sense.
Expected behavior:
[].any?{ true } == false because the array is empty.
