Dick Kriesel to the rescue again! Thanks for that background.
Comforting to know it's not merely an anomaly, but a well-considered
design decision.
It's such a cool thing to be able to do. It will change many algos here...

tPath can also be thought of as a (proper) list which makes a little more
sense. Mark W would need to answer the why.

I'm wondering how you found about about this key values array feature? I
can't find any mention of it in the dictionary or the reference manual and
it sure seems like something that should be known!

<http://quality.runrev.com/show_bug.cgi?id=7166>> dated 2008-11-28. So, thanks be
to Mark Waddingham and David Bovill for that.
For convenience, here's Mark's reply to David:
Thanks for the suggestion.
This is on the list to include for the next version. In that version with:
put tValue into tArray[tKey]
(indeed anywhere you can currently do tArray[tKey])
The meaning of 'tKey' will be extended:
1) If it is a string then it is as it is now
2) If it is a numerically keyed array starting at 1, then it will mean:
put tValue into tArray[tKey[1]][tKey[2]]...[tKey[n]]
where <n> is the number of elements in tKey
3) Otherwise it is an error.
This will allow you to construct an array containing the path to the key you
want to modify/fetch/delete dynamically.
I agree, the feature's worth adding into the dictionary and manual.
