[Newbies] Using same class names

Hi lanas,

Hmmm. Hyphens wont work they will be interpreted as subtraction messages.
Underscores won't work in squeak either. They have historically been used as assignment characters. (Old story. In an ancient characterset they rendered as back arrows. Some oldtimes loved that and no ones gotten them to update. Pharo has made a point to ween themselves but not yet squeak.)

So ALAbstractFactoryA and ALAbstractFactoryB would be good names for experimental classes. Then copy the winning experiment to your main class name. 

Do you mean for these abstract classes to have subclasses? That could have difficulties.

Yours in service and curiosity, --Jerome Peace
