class Ord 在 GHC 库中定义在哪里？

Question

GHC.Base 的来源在开头的注释部分说

The overall structure of the GHC Prelude is a bit tricky...
So the rough structure is as follows, in (linearised) dependency order


GHC.Prim        Has no implementation.  It defines built-in things, and
                by importing it you bring them into scope.
                The source file is GHC.Prim.hi-boot, which is just
                copied to make GHC.Prim.hi

GHC.Base        Classes: Eq, Ord, Functor, Monad
                Types:   list, (), Int, Bool, Ordering, Char, String

但是，虽然 Ordering 在该源文件中定义，但 Ord 不是。 Prelude 文档页面没有 Ord 的来源 link。它实际上在哪里定义？

Answer 1

Ord（和Eq）在GHC.Classes module (which is imported by GHC.Base) from the ghc-prim包中定义（它是base的依赖项）。

class Ord 在 GHC 库中定义在哪里？

Where is class Ord defined in GHC library?
