As I posted previously in this same thread, reference classes are _not_
an addition to S4, but provide an interface to the classical OOP
programming model in R, via environments and tools for those (and, also,
via some S4 techniques). The current version of the Rcpp package
illustrates how

On the subject of clarification, Reference Classes are not really an
addition to S4. They are a programming interface to allow OOP (i.e.,
C++ or Java-style) programming in R.
They do use some S4 tools but rely more on some valuable existing
techniques for dealing with environments, such as
Sorry, I was stupid:
MyRefObj - setRefClass(Blabla, .)
One can always get the generator object of an defined class with
'getRefClass()'. So:
g - getRefClass(Blabla)
x - g$new(.)
