# 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, concise 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. ## Non-Goals - Source compatibility with an existing programming language.
