Learning to read Arthur Whitney's C to become Smart

A detailed walkthrough of Arthur Whitney's compact C interpreter for a K-like array language, examining his unconventional coding style that fits an entire interpreter in ~50 lines. The author analyzes each macro and function definition, exploring the tradeoffs between code density and readability. Key techniques include heavy macro usage, implicit arguments, statement expressions, and single-character primitives. The analysis concludes that this style works best for "solved" problems where the mental model is clear before coding begins, rather than exploratory programming.
