It seems that we can't pass varargs.

extern fun printf1 {ts:types} (fmt: string, args: ts): void = "mac#printf"

extern fun printf2 {ts:types} (fmt: string, args: ts): void
implement  printf2 {ts} (fmt, args) = printf1 {ts} (fmt, args)

implement main0 () = let
   val _ = printf1 ("%s\n", $vararg("helloworld"))
   val _ = printf2 ("%s\n", $vararg("helloworld")) // can't do this, causing C syntax errors. 
in 
end

Hi,

I have not tried your sample, but there is an example use case of variadic arguments, here: https://github.com/githwxi/ATS-Postiats/blob/master/doc/EXAMPLE/TESTATS/variadic.dats

If it does not help, I may try to look further (just can’t promise).
