def zinterstore(destination, keys, options = {})
  args = []
  weights = options[:weights]
  args.concat ["WEIGHTS", *weights] if weights
  aggregate = options[:aggregate]
  args.concat ["AGGREGATE", aggregate] if aggregate
  synchronize do |client|
    client.call [:zinterstore, destination, keys.size, *(keys + args)]
  end
