What do you mean by ids? pmc->type()?
Yes, ->vtable->type().

Looking at some of the test failures, I see several instances where
t/src/sprintf test 1 is failing because
printf("0x%x", (int) -1) is 0x
but
Parrot_sprintf("%08vd", (INTVAL) -1) is 0x
Except that the latter seems correct to me, for a 64-bit platform.
For now, I'm

Aha. But say I cut it down to this:
set N1, 0.0
We have indeed gone through this before. The last time the dominant argument
was that these types of mark/unmark operations can be mis-used just as readily
as malloc/free, because the programmer has to know when and where to call them.
I'm just repeating this for everyone's benefit, not giving an
