Speaking for my personal usage, I find that the labeled form is pretty
hard to read. So I will use it occasionally when there are too many
elements in the array for me to count. The rest of the time, I will
have that feature turned off.

How about we enhance a bit the approach, and have:

        set print array-indexes on/off/auto

If set to auto, then we use the threshold?

(I'm so glad I haven't started writing the doc and the testcases yet :-).
