--- Comment #3 from Dennis <[email protected]> ---
Worth noting that scope inference also fails on foreach loops of alias
sequences:

```
@safe:
void foo(A...)(A args) 
{
    static int x; x++; // force impure for issue 20150
    foreach(a; args) 
    {
        // gets lowered to unrolled loop with `string a = _param_0;`
    }
}

void main() 
{
    scope string x = "hey";
    foo(x);
}
```

Error: scope variable `x` assigned to non-scope parameter `_param_0` calling
foo!string.foo
