Just remember that reverse loops are written like this:

for (size_t i = x.length; i-- > 0; ) {...}

Thankfully in D there is foreach_reverse :-)

import std.stdio;

void main() {
    auto array = [10, 20, 30];

    for (size_t i = array.length; i-- > 0; )
        writeln(i, " ", array[i]);

    foreach_reverse (i, item; array)
        writeln(i, " ", item);
}

Sure, but we were talking about for, not foreach. Maybe these cases in  
Phobos cannot use foreach, because they modify 'i' or they don't require  
'item'.
