Compatibility shim for Bang and Strict in Template Haskell.
As the document says, as of template-haskell-188.8.131.52,
Strict has been replaced by
Strict is the alias of
Bang, but [
Strict’s data constructors (http://hackage.haskell.org/package/template-haskell-184.108.40.206/docs/Language-Haskell-TH-Syntax.html#t:Strict)] are not provided anymore.
So this package provides these values for both versions of template-haskell.
