code: func (vb ValueBuilder) In(right OperandBuilder, other ...OperandBuilder) ConditionBuilder {
  	return In(vb, right, other...)
  }
docs: // In returns a ConditionBuilder representing the result of the IN function
  // TODO change this one
  // in DynamoDB Condition Expressions. The resulting ConditionBuilder can be used
  // as a part of other Condition Expressions or as an argument to the
  // WithCondition() method for the Builder struct.
  //
  // Example:
  //
  //     // condition represents the condition where the value "yellow" is checked
  //     // against the list of colors "red", "green", and "blue".
  //     condition := expression.Value("yellow").In(expression.Value("red"), expression.Value("green"), expression.Value("blue"))
  //
  //     // Used in another Condition Expression
  //     anotherCondition := expression.Not(condition)
  //     // Used to make an Builder
  //     builder := expression.NewBuilder().WithCondition(condition)
  //
  // Expression Equivalent:
  //
  //     expression.Value("yellow").In(expression.Value("red"), expression.Value("green"), expression.Value("blue"))
  //     // Let :yellow, :red, :green, :blue be ExpressionAttributeValues
  //     // representing the values "yellow", "red", "green", and "blue"
  //     // respectively
  //     ":yellow IN (:red, :green, :blue)"
