Well, I'm thoroughly confused already by my string example. I have
not yet really thought about the sequenciability of integers...
On the one hand, "abc" seems to be interpreted as an association with
three keys: "abc" keys -> { 0 0 0 }
On the other hand, requesting a value for one such key yields something
obviously not contained in the association.
On the third hand: Does any of the available assoc implementations actually
support multiple usages of the same key?
What I'd have expected of an assoc-conforming string, would be
access to its characters: 2 "abc" at -> either b or c
s.
