--- Comment #1 from Simen Kjaeraas <simen.kjaras@gmail.com> ---
Same results on Win32 and Win64.

Child.boop.mangleof gives the same result as Parent.boop.mangleof, regardless of final keyword, and matches the missing symbol.

Interestingly, taking the address of (new Child()).boop and calling that works
fine:
    writeln((&(new Child()).boop)());

No, this is not expected behavior.

Well, you are specifically trying to call a function that has no body, so I would argue that the linker error is correct behavior since you could potentially provide the implementation of Parent.beep in a different place. The fact that taking the address compiles is weird though.

One possible fix could be to re-resolve the function using the scope given by
`new Child()`
