Orkuncakilkaya b1ccaf08bd feat(lang): ports - port Clock { ... } in a module, bind Clock { ... } in the app
A port is a record of function values a module calls through
(Clock.now()) without naming the module that answers. A port used and
never bound, a bind missing a required member or naming one the port
lacks, and a second bind are refused; the binder must see the port, and
what it binds is checked from its own file. Reseed.
