GHC has embodied data type families since 6.8, and now type synonym families
(aka type functions) in 6.10. However, apart from our initial papers there
isn't much published material about how to *use* type families. But that
hasn't stopped you: quite a few people are using them

In my case, we had rigid type signatures all over the place. The
wiki document says that the type must be rigid at the point of the

feedback, that GADTs have
