Here's my basic defintion of ID: Two things should have the same ID if-and-only-if they will behave exactly the same, now and forevermore.

If I wrote the Perl6 code correctly (and no guarantees that I hit this moving target), then once created, a Complex object cannot be modified and is indistinguishable by behavior from any other Complex object with the same value:

Is it reasonable to have $a.id == $b.id?

No, as you can still change the properties of the objects independently. If you can't even do that, then yes.
