This is part 5 from series “Tiny Great Languages”. Final code is on Github. Part 1: Assembly. Part 2: BASIC. Part 3: Forth/MOUSE. Part 4: Lisp. Part 5: APL/K. This would be a controversial language, but it fits perfectly into the 50-lines-of-less code category. Let’s talk about APL family, and specifically – K. Created by Arthur Whitney the language is known for its terse and cryptic syntax. But it fixes one “issue” with APL – K uses ASCII symbols.
