I've been thinking the very same thing! But is "number" the data-type,
or integer and decimal the data-type (as in other languages). You see?
I don't see the point, e.g. using the Pascal family paradigm, of having
LONGINT, INTEGER, SHORTINT, REAL etc, which are data-types, and giving
them the collective name of "numbers". What would be the point?
In REBOL, the functions that operate on a "block", also work on a
string, also work etc etc etc. So is a "series" some OOP super CLASS
or something members inherent all those methods (functions).
