: Are you sure that that's not:

Either way works.  Remember I just said: "(Well, plus the notion that,
when applied to a mutator, the save/restore instruction is passed
on to the mutatee to save itself before the mutation, not after.)"
And I'd say undefine is definitely a mutator even if you don't call it
with .= syntax.  All of these probably end up doing the same thing:

    (temp $x).undefine
    temp $x.undefine
    (temp $x).=undefine
    temp $x.=undefine
    temp($x .= undefine)
    temp($x = undef)
    temp $x = undef
