Size of `UnsafeCell`
In a recent issue, Iโve noticed the following line:
UnsafeCell<T> can be larger than T in some cases
Could someone give an example of how this is possible? Iโm not sure if I can come up with one off the top of my head, and besides, isnโt being repr(transparent) a soundness property of UnsafeCell?
