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.

bump: minor type: feature Ports: port Clock { now: fn() -> int, day: fn() -> int = fn first_day } in a module and bind Clock { now: fn game_hours } where the program is put together. A module asks for what it needs through Clock.now() without naming - or uses-ing - the module that answers. A port used and never bound, a bind that leaves out a member with no default, a member the port does not have and a second bind are refused; the binder must see the (exported) port.
