Well, now i know something more. Can't we treat references as pointers? We use link list in C for the reason that an array needs continuous memory locations like 1 2 3 4 5 6 .. And when the size is big, it may fail. So, we use link list. And pushing things into a C array is not allowed. So we do this by linked list. Does perl compiler use this link list concept and keeps it hidden from us?
