Peter, I am not sure whether Front and Backscripts can be really 
considered language features. I mean that message paths are really 
part of the runtime environment in my mind. Naturally, there is no 
clear border between the language and the runtime environment since 
the language has to support its functionality. The way I look at this 
is that message paths are part of the event-driven programming model 
more than a language feature per se. Some people may look at this as 
an instantion of inheritance.
