Tables Considered Helpful
summary
Argues that tables are a concrete tool for thinking and shows working Clojure examples: using clojure.pprint/print-table, a con-table macro that forces aligned conditions, and table-driven multimethod dispatch to make edge cases explicit and testable. Demonstrates reshaping arrays, applying count across dimensions, precomputed memo tables, and a simple HTML/org-mode viewer; cites array languages (APL/J/Q, kdb+) and notes a bug in the video’s count examples with the correct implementation in Rankle repository. Shows a real table with 1.7 million pairwise comparisons on one page.
