The @trusted lambda can also be replaced with 
[std.exception.assumeUnique](https://dlang.org/library/std/exception/assume_unique.html).

Never mind me, assumeUnique is @system (or at least it's inferred 
as @system), and anyway, you can't implicitly convert 
`immutable(ubyte)[]` to `immutable(char)[]`.
