<masak> moritz_​: were you saying this should generate a warning?

* moritz_ tries to remove that error altogether
<masak> I think it'd merit a warning, but not an error.
<moritz_> the current implementation tries to be very clever
<moritz_> it does a FAIL()
<moritz_> but the coercion to Int on the failure object immediatly
throws the exception that's supposed to remain unthrown for now
