This page is still in the old style. And it isn't on the navigation column of any section. -- StewartGordon

I don't remember that it's ever been on the navigation column (though there is a link on DigitalMars:d/dcompiler.html), but adding it to the column sounds like a good idea to me. -- JustinCalvarese

Assertions are turned off in release mode

 A better solution is to make explicit what the D language does implicitly - put an assert there:


	int foo(int k, Collection c)
	{
	    foreach (int x; c)
	    {
		if (x == k)
		    return x + 1;
	    }
	    assert(0);
	}
Now, if the foreach does fall through, the error will be detected. Furthermore, it is self-documenting.

However, if assertions are turned off (for a release build) - it's back in "undefined" land again.

Better to add both, like in 

assert(0);
return 0;

However, at the moment this is not possible since the return is "not reached" according to DMD ?
