Is there any way to use more than one unpack() in a single
function call?
As Andreas pointed out, everything but the last expression
gets adjusted to one value.
You might find something like this useful:
-- Like unpack, but accepts multiple arguments:
function multunpack(...)
local ret = {}
for i = 1, select("#", ...) do
for _, rec in ipairs(select(i, ...)) do
ret[#ret + 1] = rec
end -- _, rec
end -- i
return unpack(ret)
end -- multunpack
print(multunpack({23, 45}, {-1, -2}))
23 45 -1 -2
