Sorry for dropping the ball on this. I just noticed my two patches in my patch
are still required, so I'm resending them now.

I think using 'select' here is better for consistency as we use 'imply'
elsewhere, and mixing the two might cause circular dependencies.

If you still have concerns about this, please follow up on the resend.
