The `scope` keyword means you promise not to let any references 
escape this scope. Your toString does do that, so the compiler 
might optimize this `new` away; the scope and new keywords here 
cancel each other out, leaving you with the same problem.

Still wrong code, but it'd work here because the bytes then are 
GC managed instead of stack temporaries so you still cast to 
immutable but at least it isn't use-after-free.
