The killer is for types where repr* is a real pointer:
x = [Whatever()]
y = x[:]
Now we have two physically distinct descriptors pointing at the same thing,
and so also two distinct refcounts for that thing -- impossible to keep them
in synch efficiently; "del y" has no way efficient way to find the refcount
hiding in x.
