Which is, you guessed it, a language! Okay, yeah, I didn't dive in so deep as to provide a formal specification for the language, or whatever it is you were hoping for, but if you really want to take this to silly town, I'm going to tell you that what you saw is the only valid input for this language and only specify that, so, maybe, unless you are having fun with this comedy routine (in which case, carry on; I'm certainly still entertained!), you can read between the lines? The question asking if I need to explain the universe was rhetorical, implying that I am not going to do that.
