I'm joining this thread slightly late, but thought I point to a
similar TH approach:


The implementation is very much MongoDB-specific, but we're working on
targeting different backends (package is on github, so we welcome other
hackers).  Of course, some of the issues that have been
brought up (e.g., no support for projection) still exist in
structured-mongoDB, but our goals have been more relaxed:
1) provide a type-safe interface to MongoDB, 2) to avoid QQ DSL
approach if possible, and 3) support a HaskellDB-like query interface.
