[Haskell-cafe] syb-with-class problem.

[Sterling Clover]

Sorry. I've had the patch sitting around but have been too busy/otherwise occupied to push it. This gave me the necessary kick in the posterior. HStringTemplate 0.6.6 is now on Hackage, and should work properly with ghc 7, I think.

Cheers,
Sterl.
