// Concrete Builders are supposed to provide their own methods for
// retrieving results. That's because various types of builders may
// create entirely different products that don't follow the same
// interface. Therefore, such methods cannot be declared in the base
// Builder interface (at least in a statically typed programming
// language).
//
// Usually, after returning the end result to the client, a builder
// instance is expected to be ready to start producing another product.
// That's why it's a usual practice to call the reset method at the end
// of the `GetProduct` method body. However, this behavior is not
// mandatory, and you can make your builders wait for an explicit reset
// call from the client code before disposing of the previous result.
