Can you given an example where the "fall backs" are less graceful or
less efficient? I'd think using "select()" would be _more_ efficient
(since it can avoid creating the table).
Anyway, code like:
local t = {...}
for k = 1, #t do
local v = t[k]
do_something (k, v)
end
seems clear enough...
Thanks,
