 {{{#!hs
 import Data.Type.Equality(Refl)
 }}}
 errors with
 {{{
 error:
     In module ‘Data.Type.Equality’:
       ‘Refl’ is a data constructor of ‘:~:’
     To import it use
       ‘import’ Data.Type.Equality( :~:( Refl ) )
     or
       ‘import’ Data.Type.Equality( :~:(..) )
 }}}
 But the code there does not parse, one needs
 {{{#!hs
 import Data.Type.Equality((:~:)(Refl))
 }}}
 instead (note the extra brackets!).
