Comment:

 With 7.8 or newer you'd get:
 {{{
 test.hs:5:6: error:
     Record syntax is illegal here: {f_x :: Int, f_y :: Int}

 test.hs:5:8: error: Not in scope: ‘f_x’

 test.hs:6:8: error: Not in scope: ‘f_y’
 }}}

 This was reported before, in #8612, and then closed as "not ideal, but
 acceptable".
