# Core Philosophy

  • •
    Everything is Anticipated.Control flow should be explicit and structured, minimizing runtime surprises.
  • •
    Lazy by Design.Generators and lazy evaluation are first-class citizens, not add-ons.
  • •
    Non-Blocking Core.Async/await primitives are built into the language syntax for modern concurrency.
