I do not find in Feval where the `special forms' are treated. Can somebody help me please?

It looks like from line 2272 or so in the current sources of eval.c:

      if (XSUBR (fun)->max_args == UNEVALLED)
        {
          backtrace.evalargs = 0;
          val = (*XSUBR (fun)->function) (args_left);
          goto done;
        }

>Does that help? 

I looked closely. We got it.


"UNEVALLED" indicate that the evaluation of a function must mut evaluate its arguments.

Thanks a lot.


Alin Soare.
