7:22:19tourjinit happened when I try to compile func in name of rename.
7:22:22beachIt means that you defined a function RENAME when you were in the COMMON-LISP-USER package, and that package imports the symbol SB-EXT:RENAME.
7:22:51beachFurthermore, the package SB-EXT has a "package lock" on it, so you are not allowed to do that.
7:23:12beachYou should not use the COMMON-LISP-USER package to define your own stuff. Define your own package.
7:24:28tourjinok. where can I see document about what exactly sb-ext:rename is?
7:24:50beachYou don't have to. If you define your own package and define RENAME in it, the problem goes away.
7:26:35beachtourjin: I recommend you join #clschool which is meant for basic questions like this.
7:28:33tourjinI mean if somewhere in sb-ext there already rename function defined i'd like to see what it is. ...oh ok i type in commonlisp channel again. i'll ask things on clschool channel. thank you. Mr. beach
7:29:26beachtourjin: There are probably thousands of functions in various packages in the SBCL system. You can't possibly know them all.
