Why do you want to require that?

If you don't want a constructor, don't define one.  You can pass null as 
the |constructor| parameter to JS_InitClass, and you'll get the class's 
prototype object named by the class's name in the global object, instead 
of a constructor function with a property named 'prototype' referencing 
the class prototype.
