`type.match_unknown_variant`

Pattern names an unknown enum variant.

Area 3, Logic; not declinable; the next step is usually the agent's.

example

function describe(state: DeliveryState) -> Label {    return match state {        DeliveryState.pending -> "Pending"        DeliveryState.snet -> "Sent"        DeliveryState.failed -> "Failed"    }}

jadpo checkcheck failed: 1 error, 2 files

error DeliveryState has no variant snet

--> main.jadpo:4:23

  |4 |         DeliveryState.snet -> "Sent"  |                       ^^^^ not a variant

reason: DeliveryState's variants are pending, sent and failed. Did you mean sent?
next: Use DeliveryState.sent (agent)
