My guess is that it hasn't been fined primarily because that version of an
is expression probably isn't used all that often. And if the problem is
qualifier-specific, then in order to hit the bug, someone would have to not
only use that specific version of an is expression, but they'd have to be
testing qualifiers with it as well. And I'd guess that that just isn't very
common. Not to mention, even if some code did hit it, depending on what the
it did, the bug might go unnoticed.
