Called the item assignment operator. It copies the value of the right-hand side into the Scalar container on the left-hand side.
The item assignment operator should be distinguished from the list assignment operator, which uses the same operator symbol

= symbol determines whether it is parsed as item assignment or list assignment. See the section on item and list assignment for a comparative discussion of the two assignment types.
