[REBOL] Re: Function Context Query

From: robbo1mark:aol at: 4-Dec-2001 4:21

Joel Neeely/ everybody, perhaps you misunderstood my previous post, my concern was that uninitialised local words are treated differently between contexts and function-contexts. Please see below,
>> use [my-word] [print unset? get/any 'my-word]
>> my-func: has [my-word] [print unset? get/any 'my-word] >> my-func
>> my-func: has [my-word] [print none? get/any 'my-word] >> my-func
In a use context they are initialised to the unset! value if they are not set BUT in a function context they are initialised to the none! value and that's what bothers me. I don't see a reason or logic for the distinction, can anybody please explain why these contexts are treated differently, as from what I can see it is possible to use uninitialised words in function contexts, well they're not actually uninitialised as REBOL sets them to 'none during function context creation, but WHY? What makes function contexts a special case? cheers, Mark Dickson
