[ruby-talk:02796] Re: Array.pop and documentation [was:Append alias for Array.append?]

I hope it's OK for a newbie to comment here.  Why complicate things with
three signatures? Why not just:
    slice(n,m)
where n=pos & m=length
so that:
    slice(0,1)     # slice_low        1st
    slice(0,3)     # slice_low(3)     1st 3
    slice(-1,1)    # slice_high       last
    slice(-3,3)    # slice_high(3)    last 3
