Ouch, I totally missed that. Looks like we don't have a nice
way to do this then?
I guess so. Theoretically, we could change `toStringz()` to
return `char*`; if its result is unique (we would have to change
the implementation to always make a copy), it should then be
implicitly convertible to `immutable(char)*`. But that would
break code, because it could have been used like `auto s =
"xyz".toStringz;`, where `s` would then have a different type.
So, there'd need to be an additional function, `toMutableStringz`.
