Comment:

 There is still at least one case where this is still happening - the
 operator · (char 183) comes out without parens:

 {{{#!hs
 module Test ((·), (⊃)) where
 (·) = undefined
 (⊃) = undefined
 }}}

 {{{#!hs
 module Test2 ((·), (⊃)) where
 import Test ((·), (⊃))
 }}}

 -ddump-minimal-imports outputs this for Test2:

 {{{#!hs
 import Test ( ·, (⊃) )
 }}}
