Comment(by coke):
This ticket has a deprecation notice with it that says:
{{{
These opcodes are being repurposed. They will always return a unique
memory
address of the PMC. Uses of get_addr and set_addr that would set label
values
for Sub, Exception, and related PMC types will instead be handled by
get_label and set_label.
}}}
But allison states earlier in the thread
{{{
We don't really want to provide a way to get at the raw memory address of
a PMC from PIR, because we want a copying/compacting garbage collector,
which means the memory address can change. PIR code that relies on a
consistent memory address for a PMC is broken.
}}}
So, it sounds like this is a rejection of the task listed in
deprecated.pod. Can we get a ruling on that? (And if yes, open a new
ticket and point to that one for the deprecation notice instead. The
original problem in this ticket is resolved.)
