Yes, that's right. The Template Haskell implementation in GHC 6.0 is has
one or two big holes; in ptic
- you can only reify type declarations
- type splices are not there
Tim and I are working on a new iteration of the design which we'll put
out to the Template Haskell mailing list (please join it if you are
interested in TH
http://www.haskell.org/mailman/listinfo/template-haskell). To some
extent, the things I have not yet implemented are because there's some
open questions about the design.
The things that are there should work solidly, though. I hope.
The error message is unhelpful, I'm afraid. Sorry about that.

| Subject: reifyDecl is completely broken
|
| As far as I can tell, trying to reify any declaration, even one as
simple
| as
|
| x :: ()
| x = ()
|
| will result in a message similar to
|
| ghc-6.0: panic! (the `impossible' happened, GHC version 6.0):
| dsReify reifyDecl Minimal.x {- v rNZ -}
|
| This is using the gentoo-packaged 6.0 release.
