Goals and Priorities

Ergonomics: code that is easy to read, understand and write
Familiarity: whenever a concept or notation is broadly in use from the world of programming languages or scientific notation, they should be reused if applicable.
Approachability. Simple things should be easy to do, complex things should be possible.
Expressiveness. The solution of a problem should be expressed
- in the closest way to the original problem formulation
- in a clear, natural, consice and intuitive way
Error Recovery: whenever an unexpected result is reached, it should be easy to understand what caused it, and how to recover from it.
