-- use-basic-helper.ilo — reusable helpers imported by use-basic.ilo
--
-- Public functions (exported when imported):
-- add1 n+1
-- double n*2
--
-- Private function (module-internal):
-- _doc-note — a private helper demonstrating the privacy convention.
-- Private functions are excluded from `use alias:"..."` imports
-- and cannot be named in `use "..." [...]` selective imports.
--
-- The `_` prefix marks module-private declarations.
-- Private functions are excluded from named-module (`use alias:"path"`)
-- imports and from selective imports (`use "path" [name]`).
-- In flat imports (`use "path"`), they come through but are not part of
-- the public interface and should be treated as internal implementation detail.
