I think there should never be a reason in general for a dispose call to
return an error code. The example to follow is free(3)
<https://linux.die.net/man/3/free>: if you pass this a valid pointer,
it frees it; pass it NULL, and it returns successfully without doing
anything. Passing an invalid pointer is a program bug, so there is no
point reporting this with a status code; the best thing is to print an
error message and abort.
