At the moment, one has to provide a DB specification in terms
of Database.HaskellDB.DBSpec, and the boilerplate code is generated
automagically with DB/Direct. HaskellDB-TH on the other hand provides
programmer with TH-specific functions while I think it would be much
better if these functions operated over DB/Direct specifications: you give
it a specification to get your boilerplate, as simple as that.

The opportunity to have database schema as a first-class value is appealing.

I would have already added that functionality to HaskellDB, but unfortunately,
I'm not familiar with Template Haskell yet.

I wanted to create a database table exclusively through HaskellDB; don't
tell me I'm mad, please. :)
