The following:

import std.stdio;

void main() {
 int[5] arg;

arg[10] = 3; // Compiler says (of course): Error: array index 10 is out of bounds arg[0 .. 5]

}

import std.stdio;

void main() {
 int[5] arg;
 foreach (i; 0..10) {
   arg[i] = i;
 }
}

Compiler says nothing, but we get a runtime error 'Range violation'.

Bug or design?

It is design I believe, but it should be possible for the compiler to unroll this loop at compile time and detect the out of bounds access.

That's what I thought too.
