--- Comment #1 from Dennis <dkorpel@live.nl> ---
Reduced:
```
import std.algorithm: map;
import std.array: array;

struct SmallSet
{
    ushort[13] keys;
    auto items() return { return keys[]; }
}

public struct RA {
    SmallSet members() { return SmallSet(); }
}

RA agent;

auto foo() {
    return agent.members.items.map!(x => x).array;
}
```

The problem is that members.items returns a slice to a local variable, which should be okay because you call `array` in the end, but there you hit Issue 23300.

--- Comment #2 from Dennis <dkorpel@live.nl> ---
Reopened because this issue is not limited to std.array, and is more about general return scope inference triggering errors in @system non-dip1000 code, like Johan mentions in issue 23300:

> Note that this bug does not require DIP1000, and breaks compilation since 2.101.
