      TargetSelector within(Scope... scopes)
      Specifies the scope for this selector in order to narrow down its target.

      For example, given the following classes: 

      
 record Phone(String countryCode, String number) {}

 record Person(Phone home, Phone cell) {}

      setting home and cell phone numbers to different values would require differentiating between two field(Phone::number) selectors. This can be achieved using scopes as follows: 

      
 Scope homePhone = field(Person::home).toScope();
 Scope cellPhone = field(Person::cell).toScope();

 Person person = Instancio.of(Person.class)
     .set(field(Phone::number).within(homePhone), "777-88-99")
     .set(field(Phone::number).within(cellPhone), "123-45-67")
     .create();

      See Selector Scopes section of the user guide for details.

      Parameters:
      scopes - one or more scopes to apply

      a selector with the specified scope
