-- | The call '(inline f)' reduces to 'f', but 'inline' has a BuiltInRule
-- that tries to inline 'f' (if it has an unfolding) unconditionally
-- The 'NOINLINE' pragma arranges that inline only gets inlined (and
-- hence eliminated) late in compilation, after the rule has had
-- a good chance to fire.
