[REBOL] Re: Function Context Query

Hi Romano, et al
<< Mine is only an idea, i'm not sure this is the true reason, but a none
value
can be used directly in expression like:
if ref [...]
either ref [][]
An unset value would generate an error in these cases. >>
That's exactly what I was thinking. I have no clue about the inner workings,
but I can say, from my persepctive, that I wouldn't want to use unset? to
check for refinements. The current approach makes for very readable code
IMO.
