foreach_reverse is better than ever

The first can be done turning an interval into syntax sugar for iota(1,100):
The foreach(i; retro(1 .. 100))
Otherwise the interval syntax can grow the step, as in Python and other languages (in D the step might even be a compile-time constant):
The foreach(i; 1 .. 100 : -1)

The second gives no problems if retro is well done:
foreach(v; retro(structWithopApplyReverse))
