[REBOL] [bind] Patrick's pages ; using 'local ; using bind/copy

From: rebol:meurrens at: 14-May-2003 13:07

Hello all, Bonjour Patrick, CC to the contributors of Patrick's pages on "bind", SUMMARY: visit As a fresh new rebolutionar, I appreciate the help provided by the communauty and a.o. I found in your pages all the explanations about this mysterious/magic 'bind word... Thanks... However, I have 2 small concerns regarding the "solution 3.1" of your exbind.html page. 1. I think that it would be more neat to *allways* bind, when binding your words to a local function context, by referring to 'local (the pseudo refinement allways present...) rather than relying on a specific variable. It works also for functions without parameters... 2. Another issue is that your example use "bind" rather than "bind/copy" Even if, in your small example, this is ok, I would suggest to emphasize instead the use of the /copy refinement. I think it would be stupid to create (on my own site) still another page related to bind just to publish these very small comments but I suggest instead that, after discussion of my remarks, the "main" pages on bind (namely, Patrick's pages) should eventually be updated. Everything is detailled as explained in the header partially provided below: REBOL [ Url: Credits: { 1. The REBOL dictionnary entry is at URL: 2. A good introduction by Brett Handley can be found at: 2.

However the solution proposed in 3.1 of this exbind.html page - binds the block to a variable 'nb1 which is ok, ... but binding to 'local would be more neat - does not bind/copy which is ok for the example ... but may be wrong in most cases } Purpose: { - demonstrates the use of the 'local "pseudo refinement" to bind a block to the local context of a function. - demonstrates the consequences of " bind " and " bind/copy " respectively } Usage: { demo: % browse join demo "?help" print read demo do demo } ] Regards, </marc> Prof. Ir Marc Meurrens, Brussels (be) TEL: +32 (0)2 537 2812 FAX: +32 (0)2 537 7645 EMAIL: [marc--meurrens--org] URL: REB: PGPKEY: Please don't mail me attached files, instead, use my 'exchange area' : EXCHANGE AREA: (HTTP/FTP upload/download of temporary/persistent files)
