This isn't pretty, but I've done things like this before:
local x = x or "dX"
local y = y or "dY"
local z = z or "dZ"
then you can do things like
a(nil,1) -- prints "dX 1 dZ"
along with many other variants.

PS: There are certainly several techniques (eg thought at requiring a table for opt args). I'd like to review various possibilities.
Well, I guess all is in title.
How you cope with a cas like the following:
func = function(param, optparam1, optparam2) dostuff end
Names arguments are very cool in some cases ;-)
