tldr: 1. Copying bad design is not good design. 2. If the compiler cannot reason about the code, neither can the programmer. 3. Don’t get in the programmer’s way. 4. Move work to compile-time: Programs are run more often than they are compiled. 5. Customizable memory management. 6. Concise code is not in conflict with readability, it enables readability. 7. (Leverage meta programming to keep the language small.) 8. Optimization is specialization: When you need more speed, write custom code. 9. There should be one and only one programming language for everything. That language is Nim.
