Co-Author here. We wanted to have full control over our db/sql and think it's also easier to read this way (instead of using an ORM). Similar libs got posted recently, quma will provide you with namespaces, supports dynamic SQL (conditional WHERE), has a connection pool and generally makes it nice to work with.

It's also battle tested, we're using quma since 2 years in production (pyramid app) with ~350 sql files and are quite happy.

Would be cool if someone plays around with it. Questions welcome.
