See https://issues.dlang.org/show_bug.cgi?id=21236.

It's @safe for the compiler to generate a call to it if the loop 
body is @safe. If the body wasn't safe, there would be an error 
anyway.

Do you have an example? The following compiles:

```d
void main() @nogc
{
     int[string] aa;
     foreach (k, v; aa)
         assert(v);
}
```
