This is what I do:

import std.stdarg;

void resolveArgs(inout TypeInfo[] arguments, inout void* argptr) {
  if (arguments.length == 2 && arguments[0] is typeid(TypeInfo[]) && 
arguments[1] is typeid(void*)) {
    arguments = va_arg!(TypeInfo[])(argptr);
    argptr = *cast(void**)argptr;

    if (arguments.length == 2 && arguments[0] is typeid(TypeInfo[]) && 
arguments[1] is typeid(void*))
        resolveArgs(arguments, argptr);
  }
}

void func1(...) {
  resolveArgs(_arguments, _argptr);
  func2(_arguments, _argptr);
}

void func2(...) {
  resolveArgs(_arguments, _argptr);
  // Do something with the args
}
