[luatex] variable arguments in luatex

As long time Lua coder I recently started with luatex.
I just wanted to use some Lua core functionality like this
function myfunc( ... )
for _,v in ipairs(arg) do
dosomething( v )
to discover "arg" seems to be overwritten by the command line arguments
instead of the function call arguments.
So how do vararg functions work in luatex and why is a Lua language core
variable being overwritten?
PS: Has someone already written a tikz wrapper in Lua? I like tikz, but
pgf stuff when doing non trivial math gets me crazy, thats why I want to
move this tu Lua space.
Kind regards, Axel
