Comment (by RyanGlScott):

 Replying to [comment:5 luite]:
 > Changing it to `type Uniq = Integer` turned out to be easiest because
 GHC doesn't know the data constructor for `Int64`.

 What do you mean by this?

 > And I think `Integer` is actually more appropriate here.

 I'm sure `Integer` technically works, but I am worried that we'd lose some
 efficiency by doing this, given how widely used `Name`s are in Template
 Haskell.
