Yep, that's warned for as long as I can remember, though that isn't
all that long, I suppose. Still, it's valid. Wonder how many people
do that now, completely by accident...

I'd hope that it would be one of the things we wouldn't support in
the perl 5 to perl 6 migration tool. Since it's likely always (or
darned close to always) an error, I don't think it'll be a big
problem.
