r also provides a length. Or,
if r is a random access range, then the return value will be random access as well.
retro
Iterates a bidirectional range backwards. The original range can be accessed by using the source property. Applying retro twice to the same range yields the original range.
Parameters
r | the bidirectional range to iterate backwards |
Returns
A bidirectional range with length if

reverse for mutating the source range directly.
