H. S. Teoh:
Modifying the loop variable of a foreach is, in general, a risky move.
Right. In my opinion D programmers should learn that this is the preferred idiom of using foreach ranged loops:
foreach (immutable i; 0 .. n) {}
If a D programmers really needs to modify the index inside the
loop body, then it's better to use a for() loop, that makes it
much more explicit and clear what's happening.
