I see your point. But in this case, wouldn't one consider "slot<-" as a 
part of the core language ? Even if there are further changes to the 
methods package I doubt that there will be a compelling reason to drop  
"slot<-" or changing it in an incompatible way (maybe the "check" 
argument may go away but this isn't described in "Programming with 
Data" anyway). It's possible of course, but not very likely, I think.
