It was called according the consuming sequence of stack. That is to say, the first
deferclause will be invoked as the last.

For

No.
When passing value, it will create a new copy. For pointer, it will pass the value itself.
str := "hello", str[1] = 'a' Is the string gonna modified?
No. Because the string is a constant.
string?
No. But we can assign nil to
*string
map and range is executed by sequence?
No.
==?
No.
No. &Vector{} ， new(Vector) is the same, one thing to note: new() is the only way to get a pointer to an unnamed integer or other basic type. You can write "p := new(int)" but you can't write "p := &int{0}".
