Comment (by simonpj):

 Ah I see.  I think I'll make it say
 {{{
 TestErr.hs:1:0: Invalid type signature: should be of form <variable> ::
 <type>
 }}}
 That should be an improvement. And if "foreign" is the first word (ie your
 original example).
 {{{
 TestErr.hs:1:0:
   Invalid type signature; perhaps you meant to use
 -XForeignFunctionInterface
 }}}
