Implementation Strategy

1. Config file parser (produces an internal representation of all services)
2. Service constructor (converts internal representation into executable functions)
3. Translation and Execution combinators (building blocks for services, used by #2)
4. Front End (interfaces to server framework)

Notes:

• Combinators use the Arrow interface so the resulting service is described very much like a little data flow system. Description of Arrows as combinators can be found here
• Laziness has interesting consequences and drawbacks, such as making sure a database result set is evaluated before the database connection is closed or garbage collected.
