Is it possible in S4 to define "$<-" ? If there is a slot name 'a' in 
object 'B', I find (in "S4 in 15 pages more or less")

setGeneric("a<-", function(x, value) standardGeneric("a<-"))
setReplaceMethod("a", .....

Then we can use

obj <- new("B")
a(obj)<- 3

But I did not find how to define

obj$a <- 3

Is it possible ? Is it the 'usual' way ?
