& is usually reserved for a function of type a -> (a -> b) -> b, but superrecord's & shadows it
Also, because of #17, it's impossible right now (with the hackage version) to just re-export it with a different name.
I understand that changing that name would be a huge breaking change, how about deprecating it and using something else? I'd use &=, but I must admit I haven't surveyed the conventions enough to be confident in my suggestion
