It's strange that the description of the language [0] starts using numbers without introducing them at first and then far later in the file says that they are implemented as literals. I didn't get to see the source code yet (I'm on mobile and have to randomly tap the text of the linked article to find links…), but I don't understand the point of this nor if it's just a semantic choice or actually implemented that way (I don't see how).
