I'm reading through Practical Common Lisp as a way to get more familiar with Lisp. In Chapter 4 I came across a stumbling block in the section "S-expressions As Lisp Forms." Towards the end of that section it says
"To determine what kind of form a given list is, the evaluator must determine whether the symbol that starts the list is the name of a function, a macro, or a special operator. If the symbol hasn't been defined yet--as may be the case if you're compiling code that contains references to functions that will be defined later--it's assumed to be a function name." If I try to define the following function in the Clojure REPL I will get an exception saying it was unable to resolve the symbol, but that same method will simply give me a warning in CL stating that the method mysecond is undefined. (defn myfirst [] (mysecond)) At first I thought maybe this has something to do with the fact that Clojure is a Lisp-1 vs. a Lisp-2, but the above is legal in MIT Scheme. So why is the above form not legal in Clojure? I would think it might come in handy to define a function that relies on something currently not-yet-defined. Why is this the appropriate behavior? Excuse my noise if this is already explained in the docs, or is obvious. -Ryan --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
