Bounds check

[Chris via Digitalmars-d-learn]

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?
