From http://www.digitalmars.com/d/2.0/phobos/std_range.html#Retro

Full example:

import std.range;
import std.algorithm;

void main()
{
    int[] a = [ 1, 2, 3, 4, 5 ];
    assert(equal(retro(a) == [ 5, 4, 3, 2, 1 ][]));
}


The assert should be:

assert(equal(retro(a), [ 5, 4, 3, 2, 1 ][]));

One other thing, what is the purpose of the extra square brackets next to the array literal?

This compiles fine as well:

assert(equal(retro(a), [ 5, 4, 3, 2, 1 ]));
