Implementing a doubly linked list is easier than singly linked list
Explanation:
A doubly linked list has two pointers ‘left’ and ‘right’ which enable it to traverse in either direction. Compared to singly liked list which has only a ‘next’ pointer, doubly linked list requires extra space to store this extra pointer. Every insertion and deletion requires manipulation of two pointers, hence it takes a bit longer time. Implementing doubly linked list involves setting both left and right pointers to correct nodes and takes more time than singly linked list.

Generic scoping
Explanation:
The dynamic scoping can be considered as the opposite approach to the lexical scoping. In the dynamic scoping, it does not matter that how the code is written but what matters is how's the code executes. At the time of execution of every new function, a new scope associated with it gets pushed onto the stack and this scope normally stored along with the function call stack.At that point, when a variable is referenced in a function's definition, the scope is immediately checked in every call stack to know if it returns a value.
