Comment:

 Fixed. The error now is:
 {{{

 T5863a.hs:9:31:
     Can't make a derived instance of ‛Typeable * (T Int)’:
       Deriving Typeable is not allowed for family instances;
       derive Typeable for ‛T’ alone
     In the data instance declaration for ‛T’

 T5863a.hs:12:32:
     Can't make a derived instance of ‛Typeable * (T Bool)’:
       Deriving Typeable is not allowed for family instances;
       derive Typeable for ‛T’ alone
     In the data instance declaration for ‛T’
 }}}

 As apparently there is already a test named T5863, I named this one
 T5863a.
