Thanks for the hint :)

Works great:

function pack( ... )
        local someArguments = { ... }
        local aLength = select( "#", ... )

        return unpack( someArguments, 1, aLength )
end

print( pack( 1, nil, 2, nil ) )

Is there a way to achieve the same effect with multiple return values 
which may or may not include nil?

For example:

function test()
        return 1, nil, 2
end

local someResults = { test() }

print( unpack( someResults ) )

> 1

Is there a way to get all the return values, including the ones after a 
nil?

Cheers
