Given a function, or closure, there are drop scopes for:

• The entire function
• Each statement
• Each expression
• Each block, including the function body

• In the case of a block expression, the scope for the block and the expression are the same scope.

fn main(){
    let i = String::from("i");
    let f = move ||{
     println!("{i}");
   };
}

It is unclear what the drop scope of the captured variable i is.
