[REBOL] Re: Evaluator of expressions with 'where clause

From: jan:skibinski:sympatico:ca at: 21-Oct-2002 20:02

Thanks Gregg for the good words. I play for a moment mainly with utilities because I am not ready for a big game yet :-). A question: Is there any documentation related to Rebol datatypes - aside from the stuff in the core user guide (I am using the pdf version, possibly outdated). Is there any bigger and precise picture on how those types are related and grouped in meta-types? Intuitively, most types seem to be obvious, but there are some obscure types, such as struct!, etc. What is a difference between 'any and 'any-type? I noticed that the help utility sometimes responds with the former and sometimes with the latter. Is there any special meaning in it, or is this a matter of an accidental ora historical nature? Does it have anything to do with a differentiation between the native! and the function!? Or explicit/implicit unknown argument types? I have my motivations to get it clarified, and I will describe some of them some time later. And one more question: Where does the differentiation between the actions and the functions come from? Implementation only? Thanks, Jan
