You can create classes with underscores in their name, but if you want to 
reference such class from another class, then the other class has to 
implement #allowUnderscoreSelectors as returning true, or the preference 
has to be turned on.
The class side method doesn't affect the Metaclass, so if you want to 
reference a class or send a method with an underscore in it's name from a 
class side method, then you have to turn the preference on.
