[Haskell-cafe] Conditional compilation for different versions of GHC?

Dear list,

From ghc 7.0.1 release notes:

The Language.Haskell.TH.Quote.QuasiQuoter type has two new fields: quoteType and quoteDec.

Some of my code needs to be conditionally compiled to support both version 6 and 7, what is the recommended way to do it? ref: * http://new-www.haskell.org/ghc/docs/7.0.1/html/users_guide/release-7-0-1.htm... -- jinjing
