chain <-next: [any] -> anyReturns the element right after the given argument. If the argument is
not in the chain or the argument is the last member of the chain, this
method fails. If the argument occurs multiple times in the chain, the
next of the first appearance is returned.
For backward compatibility only, if no argument is provided,
chain<-current
is returned and chain<-current
is moved to the next element.
See also chain<-previous, chain<-nth1, chain<-head
and chain<-tail.
