 3. If an argument can have multiple types, concatenate types using `or`. Example: `<STRING or CODE>`.
 4. Arrays with the same value types are written in the format `<ARRAY of TYPEs>`. The nested type has a small `s` appended at the end.
 5. If an argument is optional, the default value must be written after the type in the format `(default: value)`.
