[Template-haskell] reifyDecl and reifyType not working

[Simon Peyton-Jones]

'reifyDecl' is not a language construct; it's a function.  You need to import Language.Haskell.TH to bring it into scope.

If the user manual suggests otherwise, could you suggest improved wording?

|
| Hello,
|
| reifyDecl and reifyType seem to be recognized as identifiers and not as part
| of TH syntax by GHC 6.7.20070903.  Take, for example, the following code:
|
|     {-# LANGUAGE TemplateHaskell #-}
|
|     x = reifyDecl ()
|
| If I compile this (with or without -fth), I get the error message “Not in
| scope: `reifyDecl'”.  What’s wrong here?
|
| Best wishes,
| Wolfgang
