An iterator over the values in a set.
class ref SetValues[A: A, H: HashFunction[A!] val, S: HashSet[A, H] #read] is Iterator[S->A] ref
Creates an iterator for the given set.
new ref create( set: S) : SetValues[A, H, S] ref^
True if it believes there are remaining entries. May not be right if values were added or removed from the set.
fun box has_next() : Bool val
Returns the next value, or raises an error if there isn't one. If values are added during iteration, this may not return all values.
fun ref next() : S->A ?
