Thanks to all! With your help I have found the solution that coincide with Bronsa's (my special respect to Bronsa):
user=> (defmacro infix [e] `(let [[x# f# y#] '~e] (f# x# y#))) #'user/infix user=> (infix (5 + 4)) 9 But, this solution seems to me awkward and showing that Clojure compiler does not handling quite strictly language specification requirements. I.e., this single quote compiler should substitute itself to fulfill requirement of unevaluation arguments of macro.
