My mistake. I remeber reading something about them no longer being used but
that may have been something on the mailing list a while ago.
They have changed nature, though. I just tried:
local x=123
f = function() return %x end
x=456
print(f())
Lua4.0 returns 123 as expected, while Lua5.0 doesn't even get past the
definition of "f". It says "global upvalues are obsolete". I need to look
more closely at the new upvalues.
