[REBOL] [none idiom found?] The best shortcut word for "not none?"
From: greggirwin::mindspring::com at: 1-Sep-2006 12:56
If you use ANY and ALL, the result may be none. The mezzanine that
converts a NONE result to a logic! value is FOUND?. I was going to
suggest that we add an alternative, for cases like this, to improve
the readability.
found? all [a = b zero? a - b]
That is, I've always read FOUND? as "was the value found?", as you
would when using FIND.
Now, whenever I think I've caught something that Carl missed, I try to
think about it a bit before requesting a change, because it usually
turns out that he's thought ahead of me and did the right thing; it
just takes me a little time to see it sometimes. :)
So, I was going to say a new word would be nice but, when I stopped to
think about it a little more, I realized that all I need to do is read
it in context. In the above example, it would mean "If it is found
that all the following are true...", which couldn't be clearer (I
tried to come up with better words, and couldn't).
So, thanks Carl, and thanks to Ladislav for making me think about
this.
What else in REBOL have you found that makes you think, or read code,
differently?
