Comment(by rl):
How likely is it that this will be fixed in time for 7.0? If it won't be
fixed, we have a couple of alternatives.
1. I could remove !SpecConstr annotations from vector for now. I would
rather avoid that if at all possible because they are necessary for
performance. Also, we can't do this for DPH because we really depend on
`NoSpecConstr` there.
2. We could change the annotations to strings. That is,
`ForceSpecConstr` would become `"ForceSpecConstr"` and !SpecConstr would
look out for such annotations. Then, vector (and DPH) wouldn't import
anything from package ghc.
3. We could introduce a package ghc-annotations which would only define
the annotation types and which both vector and ghc would depend on.
Presumably, linking in ghc-annotations would have no impact on binary
sizes. FWIW, I would be in favour of doing this anyway because I've had
several complaints about vector depending on package ghc.
What would GHC HQ prefer?
