Hello,

I have the following:

```D

struct Stuff {
    int opApply(scope int delegate(Stuff*) dg)
    {
        return 0;
    }

};
void main()
{
    Stuff* stuff;
    foreach(it; *stuff)
    {}
}
```

It works fine.. but when the variable becomes ``const(Stuff)* stuff;``

It gives me:

```

onlineapp.d(13): Error: cannot uniquely infer `foreach` argument types

```

I have no idea what i should be doing, does anyone have a clue?

Try making opApply const.
