Hello ,
attempt to compile this module:
{-# OPTIONS_GHC -fglasgow-exts -fth #-}
import Language.Haskell.TH
f = match [p|0|] [|return ()|] []
produce the following error:
ghc.EXE: panic! (the `impossible' happened, GHC version 6.4.1):
typecheck/TcSplice.lhs:(128,0)-(150,44): Non-exhaust
I realize that my previous TH programs were incorrect.
But my compiant is about GHC not reporting something like "Multiple
declarations..." but panics or plainly crashes.
Sorry.

If I simply try the following:
{-# OPTIONS -fglasgow-exts #-}
module GenCG where
gdecls pbname pbniname = [d|
valGetter pbname = "Get" ++ pbniname
valSetter pbname = "Set" ++ pbniname
fldGetter pbname = "Get" ++ pbniname ++ "Field"
fldSetter pbname = "Set" ++ pbniname ++ "Field"
arrGetter p
I have the following Haskell modules:
{-# OPTIONS -fglasgow-exts #-}
module GenCG where
gdecls pbname pbniname = [d|
valGetter pbname = "Get" ++ $pbniname
valSetter pbname = "Set" ++ $pbniname
fldGetter pbname = "Get" ++ $pbniname ++ "Field"
fldSetter pbname = "Set" ++ $pbniname ++ "Field"
lift f = lift f
and that gives the infinite loop.

Hello,
I dont know if it has been reported, this looks like a bug in TH. The
program goes into infinite loop.

instance Lift (a -> b) where
lift f = [| f |]
compile :: (a -> b) -> ExpQ
compile p = lift p
printE :: ExpQ -> IO ()
printE expQ = do exp <- unQ e
