descending range function

Summary

Norbert Hajagos asked how to implement a descending range for a for loop, suggesting options like a down_to method or reversing an existing range. Richard Feldman indicated that future iterator support would handle this, but agreed that adding a List.rev function in the meantime would be a good addition.

Key points

  • The existing range_to and range_until functions only support ascending order.
  • Brendan Hansknecht suggested making existing range functions work in reverse but noted it might be error-prone (e.g., 1.range_to(x) being ambiguous).
  • Richard Feldman stated that the long-term plan is for ranges to return reversible iterators.
  • Iterators are not currently available in the builtins.

Open questions

  • None.
