def self.do(object, *messages)
  if messages.length == 1 && messages[0].is_a?(Hash)
    MultiSend.hash(object, messages[0])
  else
    MultiSend.array(object, *messages)
  end
end

.hash(object, messages = {}) ⇒ Object

Sends a hash of messages to self. The keys in the hash are the message to send to self and the values are the arguments. Used like:

5.send_hash( :+ => 5, eql?: 10 )
=> true

Multiple arguments can be sent as an array:

5.send_hash( :+ => 5, send: [:eql?, 10] )
