-- Showcase the calog export library: publish a function with calogExport, then
-- invoke it two ways -- via calogCall by name, and (a Lua convenience) by its bare
-- name, since exports resolve as unknown globals. Finally calogUnexport it and show
-- a guarded call fails cleanly instead of returning a stale result.
-- Run: bin/calog examples/scripts/libraries/export.lua

-- Invoke through the broker by name.
calogPrint("calogCall square 7:", calogCall("square", 7))

-- Invoke by bare name (Lua resolves the unknown global through the export registry).

-- Retire the export; the name is no longer resolvable anywhere.
