--- Comment #3 from [email protected] --- (In reply to Eyal Lotem from comment #2) > This is simpler -- but this simpler example isn't a bug: a pure func that > takes a mutable delegate is "weakly pure" because it doesn't take an > immutable argument. You could say that the simplified pure func takes an > explicitly mutable argument, so it is known to be weakly pure. pure_func's parameter isn't mutable. It's explicitly marked immutable. --
