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
I just added this check to DScanner:
-------------
import std.stdio;
void main(string[] args)
{
auto x = args[3 .. 2];
foreach (i; 20 .. 10)
{
}
}

/home/alaran/tmp/test.d(5:16)[warn]: 3 is larger than 2. This
slice is likely incorrect.
/home/alaran/tmp/test.d(6:22)[warn]: 20 is larger than 10. Did
you mean to use 'foreach_reverse( ... ; 10 .. 20)'?
Isn't foreach_reverse being deprecated?
