--- Comment #2 from Mathias LANG <pro.mathias.lang at gmail.com> ---
It is infuriating that the following doesn't work:
```
struct Container
{
    ubyte[] value;

        this (inout(ubyte)[] arg) inout @safe pure nothrow @nogc
    {
        this.value = arg;   
    }
}

immutable ubyte[] Def = [42];
immutable Container Default = Container(Def);
```
