OJClass API
    - Class loader API
    - More customizablity in loading source code

OJClass Bug
    - Array objects must have interface like Serializable, Cloneable.
    - Fails only for array whose elements' type is any source-based class.

OJClass API
    - getAllInterfaces() or getInterfaces() + getDeclaredInterfaces()
    - The getInterfaces() returns all the interfaces now.

OJField's lack of API
    - constructor of OJField with field initializer

ClassDeclaration Utility
    - New class objects created by makeRecursiveCopy() needs
      class-importing information

OJC Utility
    - Command line indication of metaclass

OJClass Bug
    - No metalevel information kept for newly generated classes.

ModifierList API
    - ModifierList.contains(String) may have better be sensitive
    to regular Java modifiers like "public".

OJClass's lack of API
    - setModifiers()

* OJClass Bug?
    - interface should have a superclass java.lang.Object
    * Interface is not a subclass of java.lang.Object.
