Addendum: I mean, you can get into hot water much more easily:

```
@safe:

class C {
   int x;
   void foo() const { meep(); }
}

C c;
void meep() { c.x ++; }

void main() {
   auto c = new C;
   .c = c;
   c.foo; // c.x mutates as an effect of a const call!
}
```

As far as I can tell this is totally unstoppable as global 
functions don't have const anyways. We'd need to consider the 
global scope as an implicit parameter so that it could be covered 
by constness even with global functions.
