An alternative (and I think this has also been proposed before) is to
simply drop the Graphics.UI header from the module hierarchy. The main con
here is that there's an increased risk of module name-clashes, but GHC
already solves this with the PackageImports extension.

IIRC ConstraintKinds is only required in the module that defines the
type synonym, so your module T does not need it. My guess is that
haskell-src-exts sees 'Log.Stack =>', in which we have nullary
constraint instead of a unary constraint, and assumes that's bogus
without MultiParamTypeClasses. But
