Comment (by mpickering):

 I feel that the user guide should be updated then to precisely state which
 optimisations will be performed on `INLINE` bindings.

 https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html
 #inline-pragma

 It currently states that "GHC guarantees to inline precisely the code that
 you wrote, no more and no less." which doesn't seem to be true.
