That a copy constructor is only called when initalizing a variable in the declaration. If this is true it seems like the code above declares b, then does b = a which would not call the copy constructor.

test b = a; 

for each (int i : v) {...}

for each (int i in v) {...}

How is this useful? It can save us a lot of typing, and annoying syntax errors. Say we have:
