 The code

 {{{
 x `f` y = x x
 (&) x y = x x
 }}}

 gives errors with missing backticks and parentheses:

 {{{
 A.hs:1:13:
     Occurs check: cannot construct the infinite type: t1 = t1 -> t0
     In the first argument of `x', namely `x'
     In the expression: x x
     In an equation for `f': x f y = x x
                             ^^^^^
