`semantic.standard_operation_qualification`

Standard-library operation is called without its namespace.

Area 1, Project layout and modules; not declinable; the next step is usually the agent's.

example

type DueAt = Instant {}type HomeZone = Zone {}type DueTime = ZonedTime {}function local_due(at: DueAt, zone: HomeZone) -> DueTime {    var local: ZonedTime = in_zone(at, zone)    return DueTime(local)}

jadpo checkcheck failed: 1 error, 1 file

error in_zone is a standard-library operation

--> main.jadpo:8:28

  |8 |     var local: ZonedTime = in_zone(at, zone)  |                            ^^^^^^^ needs its namespace

reason: The standard library is always called through its namespace, so the dot says who owns the operation.
next: Call temporal.in_zone(...) (agent)
