Type-safe, convenient SQLite database access.

Minimalistic library and syntax extension for type-safe, convenient execution of SQL statements. Currently compatible with Sqlite3.

Sqlexpr features:

• automated prepared statement caching, param binding, data extraction, error checking (including automatic stmt reset to avoid BUSY/LOCKED errors in subsequent queries), stmt finalization on db close, etc.

• HOFs like iter, fold, transaction

• support for different concurrency models: everything is functorized over a THREAD monad, so you can for instance do concurrent folds/iters with Lwt

• support for SQL stmt syntax checks and some extra semantic checking (column names, etc)
