It may be (I'd have to look at the paper), but it's my understanding that 
dynamically loading libraries while the program would kill that when those 
libraries can change. You could have functions which are not currently 
overridden but which a later version of a plugin could override without 
needing the program to be recompiled. The tool would mark such functions as 
final, making it so that the plugin couldn't add such an override later without 
requiring the main program to be rebuilt.
