Suppose you make a file containing a
(def foo)
form for every defn in every file and then load that first?
Does that solve the circular reference problem?

The (def g) in your example has the same effect as the (declare foo)

I discussed two problems. The first problem, which you addressed, was
mostly just a warm-up for discussing a related problem that is more
severe. Where can I put (def g) so that two files can "require" each
other?

This is not a rare problem for me. Like Mike Anderson, I work around
it by putting extra thought into which package-level dependencies I
will allow, which sometimes necessitates creating more or fewer
packages than I otherwise would have created.

I rarely run into this. The few times I have, I just do

(def g) ;creates a var g that is unbound

(defn f []
     (g)) ;ok

(defn g [] ;f will call this
     nil)

Suppose I have two functions in the same file, and one depends on the other:

  (defn foo [x] (+ 1 x))
  (defn bar [x] (* 2 (foo x)))

I can't switch their order without adding extra forward-declaration
code, which is redundant:

  (declare foo)
  (defn bar [x] (* 2 (foo x)))
  (defn foo [x] (+ 1 x))
