Pass _arguments to next method?

[Benjamin Schulte]

I already did so, and I did again as you said. But I can't find the solution for my problem. I can not do something like:

switch( _arguments.length ) {
case 0: call_sum( ); break;
case 1: call_sum( va_arg!(int)(_argptr)) ); break;
case 2: call_sum( va_arg!(int)(_argptr)), va_arg!(int)(_argptr)) ); break;
case 3: call_sum( va_arg!(int)(_argptr)), va_arg!(int)(_argptr)), va_arg!(int)(_argptr)) ); break;
}

That would be too crazy as far that I don't even know the type of the arguments that are passed. I just want to copy the current argument list of the current called method to the next one.

call_sum( _arguments ); // would only pass ONE argument
call_sum( _argptr ); // would also only pass ONE argument
call_sum( ... ); // does not work


One solution surely would be to redesign the call_sum method to something like

void call_sum( void* argptr, uint argcnt ) {
  /* ... */
}

But isn't it possible a diffent way?

Maybe this is a better example:

void debugln( ... ) {
  // save argument data to file
  // ...
  // display message
  writefln( ~arguments~ );
}
