In addition, you might want to consider using table.maxn() when unpacking multiple return values:

function test()
    return "a", nil, "b", nil

local someResults = { test() }

print( "#", #someResults, unpack( someResults ) )
print( "maxn", table.maxn( someResults ), unpack( someResults, 1, table.maxn( someResults ) ) )

Not perfect as one doesn't seem to be able to catch the very last nil value, but good enough for all practical purposes :)
