Hi all, I'm new to Java, Lisp and Clojure, so please be patient. I'm trying to make a function that behaves as follows: (my-deref x) returns x if x is a var, or @x if x is a ref. However none of the obvious options seem to be working.
- First, it seems from the api documentation that @x will work fine even if x is a var. I don't understand the following: user=> (def x 5) #'user/x user=> @x java.lang.IncompatibleClassChangeError (NO_SOURCE_FILE:0) user=> (var? x) false or user=> (def x) #'user/x user=> (var? x) false Why isn't x a var? - Second, I remember having seen a ref? function analogous to var? in the online documentation, but it doesn't seem to actualy exist: user=> (ref? x) java.lang.Exception: Unable to resolve symbol: ref? in this context (NO_SOURCE_FILE:13) Thanks in advance, Anand --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
