[Pharo-dev] Package loader question

Ciao, i have some packages with some class definition. Now the package1 define Class1 and Class2 with some reference to classA and classB defined into pachageA. packageA other hand, have some reference to class1 and class2. Now my question is: i can load the package1 and packageA without other considerations, leaving the system to resolve references as classes are loaded? Thanks for any considerations, Dario
