It is common in a recursive function to amend a global array
using the function parameter to refer to the element eg
int[10];
void foo (int i) {
foreach (x; 0 .. 9) {
t[i] = x;
foo ();
C in a for loop allows use of t[i] directly as the iterating
variable so you don't need the dummy variable x which has no
real function.
D does not. The error generated is "no identifier for
declarator t[i]". For a long time, I thought that was specific
to foreach but the same thing happens with for.
It looks like an unnecessary restriction. Am I missing
something?
