A very basic thing I don't get

[Thijs Koerselman <thijskoerselman@...>]

I feel really stupid for asking this.

local pos = {unpack({1,2,3}), 4}

print("pos size ".. #pos)

I would expect #pos to return 4, but instead its 2. A more real world situation would be to convert a vec3 to vec4 like this: 

        local vec4 = {unpack(vec3), 1}

What the heck am I missing?
