Yes. Very unfortunate mismatch :/

That said, you can pass around the argument list "as is", or even 
manipulate it to a certain extend without the need to pack/unpack 
things:

aValue = function( anObject, ... )
    return anObject:forward( aKey, ... )
end

Also, enumerating arguments requires a bit of, er, "magic":

local aCount = select( "#", ... )

for anIndex = 1, aCount do
    local aValue = select( anIndex, ... )
end

Oh, well...
