I am afraid I didn't ask my question clearly.
Michael's "solution" would give as output
(fn [b] (+ (inc a) (* b b)))
What I want as output is
(fn [b] (+ 6 (* b b)))
... where those expressions within the inner-lambda scope (of the
original nested-lambda expression) that can be evaluated by the binding
of the outer-lambda parameter -- that is, the expressions "a" and "(inc
a)" -- have been fixed with their values, but what is then output is the
resulting Clojure function definition determined by the unevaluatable
remainder of the inner-lambda scope.
It occurs to me that whether what I am asking for is possible at all
depends on how closures are realized within Clojure, but I think that
there would be a way of realizing them in terms of source code rather
than compiled code -- and that this source code wouldn't be compiled
until values for their open variables become available.

Is there some way that I can suppress the evaluation of this
expression?
((fn [a]
'(fn [b] (+ (inc a) (* b b)))) 5)

In Clojure, if I have a function call that asks for return of a
function, for example
user> ((fn [a] (fn [b] (+ (inc a) (* b b)))) 5)
I get the function name
#<user$eval4164$fn__4165$fn__4166
user$eval4164$fn__4165$fn__4166@29770daa>
But what I would like to get is an expression that defines this
function, for example
(fn [b] (+ 6 (* b b)))
Is there some way that I can suppress the evaluation of this expression?
