RebindableSyntax and OverloadedLabels
Should these extensions work together? I wasn't able to come up with a good motivating example; I was playing around with lenses, and thought a more restrictive class definition might aid type inference, though it turned out in that particular case it didn't. In the general case I think it might still be useful.
I didn't see any discussion on this, and it seemed like maybe it's an oversight.
