Good point. We really need a comparison with other languages, because some things are special. Things like this: - In rebol references are values. Series are not, you must reference them. Copies are very explicit in rebol, when they are not mentioned, better expect they do not happen. That is true for functions too, a: [] references the block in the functions code, not a copy of it. Thats why you see all the a: copy[] in code. - series-references contain a reference to a position in a series, not only to the series itself. like a cursor in a text. > Giuseppe Chillemi > > > > -- > To unsubscribe from the list, just send an email to > lists at rebol.com with unsubscribe as the subject. > > -- -Volker "Any problem in computer science can be solved with another layer of indirection.
