It’s absolutely the right answer. You autoboxed it by running a
method—`.^name`—on it. A uint can’t respond to `.^name`, so you can never
get that as the right answer. If you try assigning a negative value to it
after doing `.^name`, you’ll be able to, but if you read it back, it will
be the complement.

You seem to be asking for Raku to intentionally provoke, then recover from,
a segmentation fault, and then tell you whether or not it faulted. Is that
what you’re asking for?
