Bug 297 – Shadowing declarations allowed in foreach type lists

void main() { int i; int[] a; foreach (i; a) {} foreach (i, n; a) {} // this fails, the above don't for (int i;;) {} } I don't think this should be allowed, but I'm not entirely certain. Foreaches are, in a way, functions in their own right, passed to the container's opApply, and shadowing in nested functions or function/delegate literals _is_ allowed. I just still tend to think of foreach loops as only the better way of writing for loops, and since you can't do it with for loops you shouldn't be able to do it with it foreach loops. <g>
