Perhaps, the RFC should discuss how it helps catch this issue.

@konnov https://apalache.informal.systems/docs/adr/006rfc-unit-testing.html mentions TypeOK
with n2
too.
from examples.
Is it an issue because TypeOK
could be used to prove inductive invariants?

By the way, I guess, you would easily find such a thing with unit tests

The RFC on unit tests is about ChangRoberts, yet missed this issue. At any rate, I think these issues are generally rare for TLA+. From my experience, this is usually an artifact of the user-defined TLA+ operators, such as TypeOK
, going out of sync with the TLA+ translation of a PlusCal algorithm. I wager that the PlusCal algorithm was at some point refactored and the n2
label dropped, without updating TypeOK
accordingly.

Well, we missed this issue, because the framework is not implemented :)
