I get an error for this with dmd as of commit 05a27e287e546e8553741fffccea0059f0c11f63:

t.d(8): Error: address of variable `this` assigned to `this` with longer
lifetime

I think this was fixed by https://github.com/dlang/dmd/pull/13577 then

Re-opening, because:
- the error message makes no sense
- this is not yet tested for in the test suite
- hence, the accidental 'fix' will quietly be reverted when issue 22801 gets
fixed

The error message isn't great, but it is correctly identifying the problem.

    ptr = &storage;

*is* taking the address of `this`, and assigning it to `this`.

As in`storage` is *(this+0), and `ptr` is *(this+8)

It's saying `this` has longer lifetime than `this`. Since when does `x > x` evaluate to true?

It also still works when you add `return scope` to the constructor:
```
@safe:
struct S {
    int storage;
    int* ptr;

    this(int dummy) return scope {
        ptr = &storage;
    }

    int* get() return scope {
        return ptr;
    }
}

int* escape() {
    S s = S(0);
    return s.get; // escapes a pointer to stack variable `s`
}
```

Nevermind, it says `this` has longer lifetime than "address of variable `this`", but, it should be in test suite and the modification with `return scope` needs to error.
