Issuing a break statement will not cause the foreach loop to exit but instead
will perform another iteration before jumping out.

---
import std.stdio;

void main()
{
    int[int] test;
    test[0] = 0;
    test[1] = 1;

    bool flag = false;
    foreach( k, v; test){
        writefln("loop: %s %s", k, v);
        assert(!flag); // fails on second loop!
        flag = true;
        break; // should exit here after the first iteration
    }
}
---

output:

---
loop: 0 0
loop: 1 1
core.exception.AssertError at test(12): Assertion failure
