Milinda if you are asking about the ~' that simply allows you to quote a symbol without the namespace resolution that a backquote ` provides. If you are trying to capture a local lexical value or otherwise do not want the full namespace resolved for the symbol, then you must use an ordinary quote on the symbol since part of the job of a backquote is to provide the namespace resolution.
