Reports arithmetic and bitwise expressions with unsupported operands.
Starting with PHP 8, using the arithmetic and bitwise operators
-- when one of the operands is an array, resource, or non-overloaded object will result in a
TypeError. The only exception is the
array + array merge operation, which remains supported.
