Typos on 1.4.10 Smart Pointer

[0x5A69656C]

I tried running this code which resulted in the error codes for "error: missing 'for' in a trait impl" I tried adding the desired 'for' which resulted in the second error code "error: expected 'where', '{', '(', or ';' after struct name, found keyword 'for'

on line 7

fn deref(&sefl) -> &Self::Target {

I believe this should be

fn deref(&self) -> &Self::Target {

and on line 15

println("SBox drop itself!"); // just print a message

I believe this should be

println!("SBox drop itself!"); // just print a message
