That sounds well defined to me. If it has a predicible behaviour, even if it's not useful, it's defined.

I must be missing something.

    But it isn't well defined. In 
        $i = $i ++;

    you do not know whether the assignment will happen before, or after the increment.

      There is no good reason why that is undefined, if perl has one source code and C has no eval type function.

        There are very good reasons to let things undefined. If you specify things, it's hard to change the behaviour. Undefined behaviour can change (and history has shown that it does).

        Perl doesn't have one source code, I've 192 versions of Perl installed on my computer - all with a different source code.
