Fast and tiny expression evaluator with minimal syntax.

Project mention: Wax compiler – a tiny language designed to transpile to other languages | news.ycombinator.com | 2024-04-19

> The goal of wax is to be a "common subset" of most major imperative programming languages. By lacking the unique fancy features in each of these languages and being as boring as possible, wax transpiles to all of them seamlessly
I love the concept. I was recently studying a very small language called "subscript", with a similar idea they called "common syntax".
> Subscript supports common syntax (shared by JavaScript,C, C++, Java, C#, PHP, Swift, Objective-C, Kotlin, Perl etc.)

A programming language in Classical Chinese. Procedurally generated flowers, fish drawings, imaginary creatures, landscape paintings. In my mind, he's up there in the Olympian heights with Fabrice Bellard, Justine Tunney, etc., in terms of technical mastery and innovative thinking.
