Hi devs,
say I have:
class C a where
type F a
type F a = a
instance C Int
During compilation of "instance C Int" GHC will derive a default associated
type instance "F Int =
Int". That instance has no location information and so any errors that it might
cause will have a
very uninformative source code location 1:1. I want to fix this but I'm not
sure whether it is a
good idea to add location information to automatically generated code. Do we
make any assumptions
that derived code should have no location information?
