Adventures in homoiconicity
summary
Demonstrates concrete uses of Clojure homoiconicity: a Quil sketch reads its current namespace and visualizes the number of public defs (example showed 8 public defs) to drive a 0–255 background color, uses macroexpand to view expansion of macros, and treats code as EDN to store and eval generator programs. Shows a Twitter bot that keeps the generator as data (Twitter bot stores generator code) and a self‑healing example that detects a divide‑by‑zero in average on an empty vector, selects a patch and replaces the failing function so tests pass.
