comp: remove most imports of Data.Generics
#722
Conversation
99% of the uses of the `Data.Generics` import from `syb` was to qualify the names `Data` and `Typeable`, but these have long since been available directly in `base` along with `DeriveDataTypeable` for many years now. The `syb` exports are in fact just re-exports from base. Migrate most of the code to just use `Data.Data` directly instead. At the same time, this touches up some of the import lists to be a little more consistent, but is otherwise functionally identical. Signed-off-by: Austin Seipp <[email protected]>

Are you removing this comment, because it's no longer meaningful? If it's still meaningful, I'd leave it in. (I don't offhand understand what it's saying.)

You reorder a few import lists, and I don't quite understand your choices, but OK.

Did you intend a space here?

And the only place we have Handle in a data structure needing Data is here in IConInfo (ICHandle), so you've chosen to put the instance here? Ok.
