This has already been fixed, you just need to use

as it introduces a breaking change.

I just tried that flag on run.dlang.org, and although it fixes 
the case I posted earlier, it doesn't fix this one:

```d
string test(const(ubyte)[] arr)
{
    import std.string;
    return arr.assumeUTF;
}
```

Shouldn't this be rejected as well?
