Hi Andrew,

Indeed, it could be useful to chain two or more REVERSE/PART:
>> x: [1 2 3 4 5 6]
== [1 2 3 4 5 6]
>> reverse/part reverse/part reverse/part x 2 2 2
== []
>> x
== [2 1 4 3 6 5]
However, maybe it is more common to have it chained with other
functions, where returning the series at the same position as the
argument would be more useful. What do you think?

Gabriele.
