If I understand Manu correctly the first should compile, and
the second should error, just like if you replaces shared with
const in the above.
Why is the second an error?
Right, for the sake of the thought experiment, replace shared
with const.
The first is an abomination (casting away const)... the second
is just a no-op.
I missed that the third example was *p3 = p; not *p3 = p2;
