Re: How to remove verbosity from the data passing mechanism using alist or plist ?

[Fren Zeee]

Let me sharpen my question on the conceptual issue. Note, the original
question has split into several ways and we are just on this one for
now in this reply of mine.

What's the meaning of (cons 1 2) versus (list 1 2) ?

cons expects the second argument to be a list and inserts the first into it.

Thus (cons 1 2) did not make sense to me. Perhaps, after a few years I
have forgotten or dulled in my concepts.

(list 1 2) <=> (cons 1 (cons 2 () ))

Anyway, I can move forward with this unless you or anyone has
something enlightening to add and someone does come and start telling
me I need to go and take a class in lisp.

We can move to the
