computer language, language design, Lisp, little programming language, LPL, programming language, syntax
I’ll pick up with the language I began describing last time in a future post. Right now I want to pick up the thread of Little Programming Languages (LPLs) and use several examples to illustrate what underlies a programming language. (And as it turns out, these are “little” only in a certain sense.)
This first example, LPL-3, is Lisp-like and, because of that, is fairly orthogonal. Even better, it’s probably actually usable, although — like Lisp — it doesn’t have the cleanest syntax (languages like Python have really spoiled me).
