prim-reg!

File an x-lang value into the catalog under ns/method.

The producer half of the registry protocol: library implementations register

under the same stable identities as C prims. Registration prepends, so a

re-registration shadows the older entry on lookup. Returns nil.

Parameters:

• ns : SYMBOL — Namespace symbol, e.g. ‘float
• method : SYMBOL — Method symbol, e.g. ‘+
• value : ANY — The implementation to register (fn, op, or any value)

Examples:

(do (prim-reg! 'demo 'twice (fn (_ n) (* n 2))) ((prim-ref 'demo 'twice) 21)) => 42
