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.

**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.
