ADR 03: defnz is the primary function form

Date: 2026-06-16

Context

clj-zig needs a primary form for defining a Clojure-callable, Zig-backed function.

Decision

Use defnz for Clojure-callable Zig-backed functions.

Consequences

It reads as defn plus Zig and keeps the mental model anchored in ordinary Clojure function definition: "I defined a Clojure function whose implementation happens to be Zig."

Alternatives

An explicit compile/load/bind sequence was the thing to avoid; it exposes the native machinery the design wants hidden.
