I think this was the impetus for foreach_reverse, or at least it is one
place where it is pretty handy. Don't remember what all there is in D1,
but in D2 you could do something like
foreach_reverse(i; 0u .. 10u){
// iterates over 9,8,7 .. 1,0
}
for more complex iterations, I suppose you're stuck with
foreach(i; retro(somerange)){
}
or tired old for loops

hi everybody,
recently i was hit by an old-known programming error, using unsigned int in for
loops could get into infinite traps:

for-loop-with-an-unsigned-index
so, i D (1 or 2) is counter-attacking in some way (for example, disabling
implicit casting of (-1) to UINT_MAX).
cordially,
eles.
PS i really like being able to use an unsigned int for those loops, both for
logical and for programming (large values of the loop index), while still
avoiding such traps. thanks.
