[REBOL] Re: Annabelle Content Management System

From: sabufrancis:rediffmail at: 14-Sep-2007 1:35

Hi Yes Prolog is quite a useful language. The concept of 'backtracking' is very powerful. In fact, I think (not verified) many important concepts originated in Prolog and Lisp, two of the oldest languages. It also handles data and meta-data structures very nicely. I had used a variant of XML in Prolog (which I used to call 'proXML') that overcame many of the problems that Carl had pointed out in XML. Anyway, I am probably digressing ... I find Rebol also a very good language to work with. I think it can also handle data+code together (data turning into code, code back into data) which can be very useful. Now if someone has figured out a way to do backtracking in Rebol and do things like 'findall' ( a predicate in most Prolog to collect data together)... well that would be really wonderful.
