[REBOL] zero based indexing
From: deadzaphod::flyingparty::com at: 6-Jul-2001 3:02
I'm a bit confused by the heated arguments about series indexing in rebol.
rebol does not provide an array subscript operator, so virtually all series
access is done via functions. why not just create a set of new functions
(with different names so we don't break anything) that use zero (or whatever
you want) as a base, and you can just use those instead of
pick/at/poke/index? in your scripts, without needing any change or patch to
rebol itself.
here's some examples (with names based off the normal functions) for zero
based indexing:
pick': func [[throw] l i][first at l i + 1]
at': func [[throw]l i][at l i + 1]
poke': func [[throw] l i d ][change/only at' l i :d l]
index': func [[throw] l ][-1 + index? l]
what would an internal change to rebol do for us that this doesn't? (other
than the improved speed by making these native! functions) (I realize I'm
probably missing something important, judging by the length of this thread)
