hsLTyClDeclBinders :: Eq name => Located (TyClDecl name) -> [Located name]

Returns all the binding names of the decl. The first one is guaranteed to be the name of the decl. For record fields mentioned in multiple constructors, the SrcLoc will be from the first occurrence. We use the equality to filter out duplicate field names.

Each returned (Located name) has a SrcSpan for the whole declaration. See Note [SrcSpan for binders]
