This is an odd request.

I often pass functions to functions in order to simulate a C switch
statement, such as in a language translator:

  commands = {
    'add': doAdd,
    'subtract' : doSubtract,
    'multiply' : doMultiply,
    'divide' : doDivide
  }

  nextCommand = parseCommandLine( line )
  invokeCommand( commands[NextCommand] )
