Where has the special built-in inline function gone?

Hi all,

For the first time, I wanted to use the special built-in inline function.
To my dismay, I can't find it anywhere! Here's a minimal example:


module Main where

import GHC.Prim

f x = x + 1
{-# INLINE f #-}

g h x = inline h x

main = print $ g f 1


$ ghc /tmp/Repro.hs
[1 of 1] Compiling Main             ( /tmp/Repro.hs, /tmp/Repro.o )

    Not in scope: `inline'
    Perhaps you meant `unlines' (imported from Prelude)
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.4.1
