Should the following two uses be a compile-time error?

I would like the second to either be a compile-time error or
automagically use a negative step.

So we need to use a negative step in iota() or use a for loop
   foreach(i; iota(10, 0, -1)) // as expected

The parameters can be runtime values. Auto-magically using a negative 
step would hence be a bad idea.
