Is there a way to write something like this?
No, unfortunately only expressions can be spliced. I'm afraid, You'll
have to build the declaration manually.
Do you think its worth opening a ticket?

I feel this is much harder to read..
Maybe I'm still not used to template haskell

    let names = [ "m", "elc", "stc2", "elc3", "st2", "el2", "st2", "el3" ]
        [ m, elc, stc2, elc3, st2, el2, st2, el3 ] = map mkName names
    in classD [] 
              (mkName $ (classElem ng) n) 
              names
              [funDep [st2,stc3] [st3],FunDep [el2,elc3] [el3]] 
              [sigD (mkName $ (elemName ng) n) 
                    (ForallT [a,st,el] 
                             [] 
                             (appTn (varT m) [ conT elst, varT elc, conT elst, varT elc, varT stc3, varT elc3, varT a]
                             )]
