1. Readability
2. Proper encapsulation (to have interface and implementation separated)
3. Re-use (the same function must be refactored)
4. Maintainability (because of 1..3)
5. Safety (proper bodies are defined on the context where they have no
access to the caller's context, otherwise than through parameters)
6. Deployment (proper bodies can be put into a library, have versions etc)
7. It is not Ada
