Marco Leise:
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);
}
Bye,

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'.
foreach_reverse(i;0..array.length) writeln(array[i]),i--;
