[REBOL] Re: Run Time Object Type Identification

From: greggirwin:starband at: 2-Oct-2001 10:08

Hi Phil, I think the best approach will depend on what it is you need to accomplish. Because objects are cloned, they are very independent. If you want to categorize objects, you could add the 'type or 'kind word as you did in your example. If you want to find if they support one or more interface mechanisms, it should be easy to write a little function to do that (can-do? supports? supports-all?). I'm too much of a newbie to suggest what is best, but my gut tells me that adding type-info blocks to all objects, to support RTTI, is something to reserve for cases where you really need it, rather than making it a general rule. --Gregg
