- reified-slset-delete! RS SYM_1 ...procedure
Adds the SYM_i symbols not already in the reified slset RS parameter to the set, mutating it in-place. New symbols are added to the front of the list, but no guarantees are made about their order.
Runtime is O(n+m), with n the size of the RS set, and m the number of symbols to delete. As a special case, if none of the symbols occur in the set, it is O(m), because filtering of the set is skipped.
Returns RS (for convenience only, the set is updated in-place).
