Thank for the suggestion. We've considered it a couple of times before but there are downsides that get in the way:
* The related mathematical concept of sets is unordered.
* It isn't clear what ordering should be returned
by set operations like intersection, union, and
difference especially if we want the first two
to be commutative and if we want consistent
in-place and data removal options.
* It gets in the way of existing performance optimizations
some of which are significant.
* Other programming languages don't seem to have
found compelling the need for this.
So yes, it is something we could do, but probably shouldn't. |
