1. Test macro call with no parameters. "Teapot" = "Teapot" 2. Test macro call with one parameter. "Left Testing Right" = "Left Testing Right" 3. Test macro call with many parameters. "Left x Middle y Right" = "Left x Middle y Right" 4. Test macro call as a parameter of another macro call. "Left Ostrich Middle Left Wombat Right Right" = "Left Ostrich Middle Left Wombat Right Right" 5. Test expression recursive macro call. "[X[[Walrus]]Y]" = "[X[[Walrus]]Y]"
