Yes, except the former illustrates that dice() requires you to use the
@_ variable rather than $_ as in map and grep. I'm also partly trying
to illustrate the analogy to
L(that_function($l->map(\&fx)))->map(\&fy);
where calling dice() turns @{$l->map(\&fx)} into @_ and allows you to
chain the processing rather than having an LR chain within an RL chain
which is then wrapped and fed into yet another LR chain.
As you can see, I could use some help making that crystal clear :-)
