default

The default keyword marks a module's default export (the value imported when no specific name is given) and is also used as a fallback branch in some match/switch forms.

Syntax & Example​

export default fn main() {
    print("entry point");
}

Use Cases​

  • Designating a module's primary export.
  • Providing a fallback case in pattern matching or switch-like constructs.
  • Pairing with export to define a single, prominent module member.
