[REBOL] Q: Functions and the visibility of words

From: jhagman::infa::abo::fi at: 25-Apr-2001 2:39

Hi, I have been playing with REBOL for a some time but I still am curious about the word visibility scheme chosen by Carl. When a word is definied inside a function it is visible also outside the function (after the invication of the function) unless explicitly specified local. This seems to be a different approach to most of the other programming languages (at least that I know :). The disadvantages are obvious, it is easy for the programmer to introduce unwanted side-effects, but what are the advantages this scheme introduces? -- Jussi Hagman CS in Åbo Akademi University Studentbyn 4 D 33 [juhagman--abo--fi] 20540 Åbo [jhagman--infa--abo--fi] Finland
