String templating elevated to "tagged templates" [0] which dispatches template on your own function is suprisingly acceptable solution. I'm using it to drive mssql sql generation [1] and it works really well with type system around combinators. It's perfect, extremely lightweight way to achieve embedded dsl like experience.
