A few questions:

Eh... can you give an example? Or, does this help to clarify? :

(- (+ a b) c)
What I mean is:
(infix '(a + b + c + d))
=> (+ (+ (+ a b) c) d)
because + is left associative, while
(infix '(a ^ b ^ c ^ d))
=> (^ a (^ b (^ c d)))
because ^ is right-associative.
Your code handles all operators as if they were all left associative.
The URL you gave explains how to handle right associative operators.
