Comment:

 Excellent point.  That is bad. I'll fix.

 Meanwhile, in both cases you have
 {{{
 deriving instance Data (Expr Const)
 deriving instance Data (Expr Var)
 }}}
 Question: do you really want this?  You're generating more or less the
 same code twice.  Why not write this?
 {{{
 deriving instance Data a = Data (Expr a)
 }}}

Comment (by ronwalf):

 In this case, (a) has the wrong kind (*-*), so trying that line gives:

 #WouterTest2.hs:396:39:
 Kind mis-match
 Expected kind `* - *', but `a' has kind `*'
 In the type `Expr a'
 In the type `(Data a) = Data (Expr a)'
 In the stand-alone deriving instance for
   `(Data a) = Data (Expr a)'
