[REBOL] Contexts was: Special word

From: lmecir::mbox::vol::cz at: 8-Sep-2001 3:17

Hi, Rebols! Summary: Romano discovered an interesting "feature": the System/words object isn't the Global Context! Contexts.html ) needs a revision! Romano:
> Now i want "stress" you with another question, about your "Special Word" > concept. > > I make a word: > > >> word? first to-block "foo" > == true > > The function Special return true for: > > Special? first to-block "foo" > == true > > "foo" is not in system/words: > > find first system/words first to-block "foo" > ==none
Amazing! You revealed, that there are words that cannot be found in (first system/words). That invalidates some parts of Contexts.html: 1) The first one is the statement, that the System/words object is the Global Context. If I define the Global Context as the collection of all Global words, than I get: global?: func [ {find out, if the given Word is a Global Word} word [word!] ] [ same? word bind word 'system ] gw: bind first to-block "foo" 'system global? gw ; == true find first system/words gw ; == none It is immediately obvious, that the System/words object is only a part of the Global Context! 2) The second victim is the Visualize-context function as you pointed out, because it can find only the words from System/words.
>Another case:
o: context to-block "foo2: 3" find first system/words first to-block "foo2" ; == none find first o first to-block "foo2" ; == [foo2]
> Now: "foo2" is in the context "o" but not in the Global context.
Not exactly, you can find the corresponding Global word as above, but not in the System/words object!

Excellent work Romano! Ladislav
