I've not touched R3 yet. Will wait until I've actually a need for it, since I've no
time just to play with it. (Plus I loath software upgrades. Seems there's one or two
a week these days if you've a reasonable amount of software installed, and with them
all having the potential to waste hours of your time should they stuff something up...)

Seems all the datatypes have a number...

file?: native ["Returns TRUE for file values." value [any-type!] 42]
so probably something as simple their addition to REBOL.
Is there to be a video datatype in R3? I see there's a video tag planned for HTML 5.
Hopefully REBOL plans to keep up.
