Dynamic argument list in a DefineEngineMethod ?

The title basically says it all. But is it possible to have a dynamic argument list when declaring a DefineEngineMethod?
This is relatively easy using a ConsoleMethod eg:
For a normal function you would do something like this:
------------------------
Does something similar work for the user-defined args in a DefineEngineMethod?
Eg. Converting the above console method, could I go and do something like this:
(or is there an actual way to do it with a DefineEngineMethod, it doesnt like the ... )

ConsoleMethod( SimComponent, addComponents, bool, 3, 64, "%obj.addComponents( %compObjName, %compObjName2, ... );\n"
For a normal function you would do something like this:
#include <stdarg.h>
#include <stdio.h>
void print(char *one, ...)
{
va_list va;
char *p;
for(p = one; p; p = va_arg(va, char *))
{
puts(p);
}
va_end(va);
return;

So, it looks like I might have some fun over the weekend trying to convert DefineEngineMethod into a variadic macro

I was planning on removing ConsoleMethod/ConsoleFunction entirely. So sadly, it's not much help :(So, it looks like I might have some fun over the weekend trying to convert DefineEngineMethod into a variadic macro

Maybe a template version of that would work - though my template programming skills aren't up to that task it seems like it should be possible.

I'm not aware of a way to do this unless you were to change the trampoline and template code. I would be very interested to see it done though.

I could be mistaken - anyone else care to chime in on this one?
