However, you went on to say

which is where we differ. I much prefer to discourage the use of ivars ('@'
variables, or "instance variables") and stick to the object contract/API
internally. I use Struct in production code because it's fabulously useful.

Just because something doesn't work the way you insist it must doesn't mean
it's broken.
