[Simon Peyton-Jones]

All true!  Good suggestions.  

Are you getting on all right with TH now.  The mailing list has been
rather quiet recently.

| 
| 
| Hi,
| 
| The GHC 6.2 User's Guide has some misleading information w.r.t.
| template haskell.
| 
| It still uses Expr instead of ExpQ. It refers to Tim Sheard's notes,
| but doesn't have the link
| 
| http://research.microsoft.com/~simonpj/tmp/notes2.ps
| 
| It should also warn that not all of the features discussed in the
above
| notes are implemented.
| In particular, the way to get TH is still to import
| Language.Haskell.THSyntax, not Language.Haskell.TH.
| 
| The example doesn't compile under 6.2. The attachment corrects this.
| 
| A note that TH is rapidly evolving and that the API is likely to
change
| incompatibly between
| compiler releases might not be out of place either. (I know that such
| warnings are present
| in the literature and in some places on the mailing list, but language
| users who are not
| part of the FP community look to the documentation first.)
| 
| Best Wishes,
| 
| Greg
