Can someone help confirm whether I understand correctly the semantics difference between the final-line eval of
x^
vs.
x*
?
It seems like either one evaluates the contents of the `box`, and would only make a difference if you tried to use `x` afterwards? Essentially if you final-line eval `x^` and then decide you want to continue that snippet, you can't use `x` anymore because it's been moved. Awkwardly, it also hasn't been assigned so I'm not sure the box is accessible anymore?

More or less. x^ moves the whole box whereas x* copies the contents of the box. > Awkwardly, it also hasn't been assigned so I'm not sure the box is accessible anymore? Yes, if you move something and don't assign it then it gets dropped, same as rust.
