Suppose at my REPL I do... (defn direct-report-oneplustwo [] (println (str "Direct one plus two is " ((fn [n] (+ 1 n)) 2) ".")))
...then I presume that the compiler has compiled my direct-report-oneplustwo function, and that this has included compilation of my anonymous function (fn [n] (+ 1 n)). So that now if I run... (direct-report-oneplustwo) ...at my REPL it just needs to run this precompiled code to tell me my answer 3 - no additional compilation required. So far so good. But what if instead I do this at my REPL... (defn adder-make [m] (fn [n] (+ m n))) (defn indirect-report-oneplustwo [] (println (str "Indirect one plus two is " ((adder-make 1) 2) "."))) ...Now at this point, both adder-make and indirect-report-oneplustwo should have been compiled. But unlike our first approach, the anonymous function (fn [n] (+ 1 n)) has not yet been created by (adder-make 1) and so presumably (??) has not yet been compiled?? I am presuming that it is only when we actually run the report function... (indirect-report-oneplustwo) ...that (adder-make 1) is actually run, thereby producing the anonymous function (fn [n] (+ 1 n)), which then gets compiled right then-and-there, immediately followed by its execution?? But maybe this is wrong!? Maybe instead somehow the compiler managed to "pre-compile" the anonymous function as part of the compilation of adder-make? Maybe there is a stored compiled "template" function, the bytecode for which gets "rolled out" at runtime in slightly different ways depending on the parameter m?? Can anyone clarify for me what happens here? Thanks, Mark. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
