Maybe sth like that
(defn assoc-in-maybe-creating [coll keys creator-fns value] ...)
so it can be used:
(assoc-in-maybe-creating
[ {:a (sorted-map :X 1, :Y 2, :Z 3)
:c (sorted-map :X 1, :Z 3)}
{:b (sorted-map :X 1, :Y 2, :Z 3)}
{:f (sorted-map :X 1, :Y 2)}]
[0 :b :X]
[vector
Some "Thinking out loud" here...
My last concern with assoc-in & arrays has to do with how it is
currently used for maps. The way it creates elegant nested structures
is nice, and it requires very little understanding of the current
structure of the map.
However, assoc-in has a few more constrai

But this does:

I don't think so.

The following doesn't currently work:
user=> (assoc [] 1 :a)
#
So I say this should be map only. Granted, assoc-in already has this
issue.
Also, what do you mean by your question "Where would the default go"?
I don't understand what you're getting at yet.
