Schwartz's name is also associated with the Schwartzian transform , an algorithm to efficiently sort a list according to a computation, without repeating the computation many times for each element of the list. He also coined the name spaceship operator for use in his teaching, because it reminded him of the spaceship in an HP BASIC Star Trek game.
