Simple test case:

-- Test.hs
module Test where

data X = X

Output:

$ brittany Test.hs
["","","data X = X"]
-- Test.hs
module Test where

data X = X

Not sure what that's about...

Thanks. Never noticed, because my default testing ignores stderr. Now I wonder if I can make git warn me when making any commit containing non-commented "trace" strings.. someone must have written such a hook already.

You could write your own trace functions and mark them as deprecated like undefined in ClassyPrelude.

Yeah that is certainly a better idea than hooks. I'll have to add something along those lines to qualified-prelude.
