Design in Practice in Practice
summary
Explains how the Clojure/core team turned a problem — no symbolic syntax for JVM array classes — into a concrete feature in Clojure 1.12: they prototype ideas in Google Sheets decision matrices, choose a symbol-based syntax placing the class in the namespace and a numeric dimension token after several iterations (nine patch versions during alpha), write implementation plans that map exact code changes, catch regressions with a regression test of hundreds of projects, and ship the feature with only one minor bug reported.
