Hiya Patrick:
Here's a different approach:
Remove the assignment to 'private-room
Now you have
context [
a: b: 2
set 'public-fn func [][print [a]]
]
At this time, 'public-fn is still 'public'
but 'a, 'b are now 'hidden', inaccessible from
the outside world.
but of course, you can't make copies of the function.
