Hmmm... perhaps this is just a lack of imagination on my side, but... how would superfluous parameters ever matter? After all, what you don't know cannot hurt you. As far as missing argument, a simple assert would suffice, no?

local function Fussy( parameter )
    assert( parameter, 'missing parameter' )
end

local function Fastidious( parameter, ... )
    assert( parameter, 'missing parameter' )
    assert( ( function( ... ) return select( '#', ... ) == 0 end )( ... ), 'superfluous parameters' )
