Hi guys, given a mutableSet, I’d like to remove all the items from a collection, and then just get X items from it. For example

myMutableSet.removeAll(collection)
myMutableSet.take(x)

now I’d like not to use take since the set can contain millions of items and I’d like not to copy all in a new set..any suggestions?

There is no constraints on the “which” X items to take..random is fine

[Andrea Giuliano]

alternatively, I’ll be happy to move the set into a list, as long as the items won’t be copied..

The items themselves will not be copied, only their references, so if that satisfies your constraints, then the code above is fine
