Evaluates the operand expression
Converts the result to a numeric (double) value
Adds 2 to the value
Returns the incremented result

Examples:

{
  "Example1": "$(++2 8)",
  // Result: 10

  "Example2": "$(++2 5)",
  // Result: 7

  "Example3": "$(++2 TestData[2])",
  // Where TestData[2] = 8, Result: 10

  "Example4": "$(++2 0)",
  // Result: 2

  "Example5": "$(++2 -3)",
  // Result: -1

  "Example6": "Employees.Where(e => (++2 e.Age) > 50)"
  // Filters employees whose age plus 2 is greater than 50
