Hi David,
Could we get a separate LANGUAGE pragma just for equality constraints?
I think we should, and I don't think we'd even need to introduce a new pragma, since there's already a perfectly good one: -XTypeOperators! After all, there's nothing really that special about (~) other than some typechecking details. A fix to Trac #9194 [1] would give us this.
