when you access an array index that does not exist, you get an 
exception... so what is the inconsistency? Of course in a language that 
allows you to access variables that do not exist yet, it makes sense to 
allow the access to an array index that does not access too... for 
example why should "print a" succeed even though a does not exist, but 
"print a[1]" fail if a does not exist?
