Nested Replication

Because of automatic replication, each value in a list can, itself, be replaced with a list of the same type. This process can continue to any depth.

Example

myList = {11, 100, -2}
myList * 4           //
This results in the list, {44, 400, –8}.
myList = {{2, 5}, 0, {400, -3}}
myList * 4         
// This results in the list, {{8, 20}, 0, {1600, -12}}
