Or possibly simpler:
do
local function _fact(n)
if n > 1 then return n * _fact( n - 1 ) end
return 1
end
fact = _fact
end

Ok, call me stupid, but a recursive function in my book would be one
that can call itself and is self-contained.
If I do something like
function fact(n)
if n>1 then
return n*fact(n-1)
end
return 1
end
then this is _not_ a self-contained recursive function, since it relies
on calling itself through the variable named fact. If I do
factx=fact
fact=nil
print(factx(6))
this does not work. We had some previous discussion about recursive
stuff here (with some fairly esoteric code partly), but what would most
likely be the _simplest_ way to get a self-contained recursive function?
