[Haskell-cafe] HSTringTemplate and syb-with-class

[Sterling Clover]

You don't need to derive ToSElem -- you get the instance for free if
you derive Data. Import GenericWithClass to get the instance for Data
from syb-with-class, and import GenericStandard for use with Data from
the vanilla syb that comes with GHC.

Cheers,
Sterl.
