A strong property of block type has "copy" setter semantics, not "retain".
This is consistent with the behavior of assigning into a __strong l-value,
and it's also necessary for ensuring that the ivar doesn't end up a dangling
reference. We decided not to change the behavior of "retain" properties, but
just to make them warnings/errors when of block type.
