TurKit is a Java/JavaScript API for running iterative tasks on Mechanical Turk. You can safely re-execute TurKit programs without re-running costly side effects on Mechanical Turk, like creating new HITs, but still write your program in a straightforward imperative manner -- there is no need to unravel the program into a state machine.
