I suspect I will be asking more questions, so in order not to start another thread I will post below :)
Why ((comp - +) -3 -4) => 7 but ((comp Math/abs +) -3 -4) => Error? java.lang.Exception: No such namespace: Math (NO_SOURCE_FILE:1) [Thrown class clojure.lang.Compiler$CompilerException] and ((comp #(Math/abs %) +) -3 -4) => 7 Is there an inherent difference between java and clojure functions, so Java functions can't be passed as arguments? Or am I missing something? How can I pass a static java function to another function? A member function must be trickier because this must be supplied, but perhaps a macro can be created that results in a function that would capture this and call the member function appropriately ...
