Ah, things are starting to make sense!

should "new P2, I0" be "get_temp P2, I0" given what you said on the
first line above?

Also, it would be nice to have

        new P0, list, 65
        
to pre-extend the list, as the compiler knows in advance how many args
it's going to push. But I'm bikeshedding now :-)
