--- Comment #5 from John Colvin <john.loughran.col...@gmail.com> --- Apologies for not noticing the changes, I didn't notice the bug in the old implementation. What is the way forward here? The old behaviour was unexpected (why remove qualifiers?), inconsistent (didn't happen for builtins) and undocumented. I would argue that it's a straightforward bug and we should just say it's now fixed, perhaps adding a warning and a special changelog entry. --
