Several points:

EMACS:	The easy parts are written in LISP, the hard parts are written in C.

  Actually I like the argument about EMACS being written in TECO.  EMACS stands
  for Editor Macros so I guess it is written in LISP.  I.E., LISP is merely a
  MACRO language :-)

  The "editor engine" part of EMACS is, however, written in C.

  (I happen to hate using EMACS although I think the editor engine in it is
  pretty amazing)

LISP:  Just try to write a terminal screen optimizer in it which is fast enough
       to be used in a real editor.

C:  This isn't really a high level language, it's portable assembly language.

And it really does have dynamic typing and all that:

	/* Graph function user types in... */

top:	printf("Type function in terms of variable x: "); gets(buf);

	sprintf(buf1,"main(argc,argv)char *argv[];{int x=atof(argv[1]);"
                     "printf(\"%%f\n\",%s);}",buf);

	sprintf(buf2,"echo '%s' >tmp.c;cc tmp.c",buf1);

	if(system(buf2))
		{	printf("Try again\n");
			goto top; }

	/* Now graph the function... */
	for(x=0.0;x!=1.0;x+=.001)
		{
		sprintf(buf,"./a.out %f",x);
		popen() etc...
		}

So what we really need is a "OBJ *compile(char *func)" function in the C
library to compile functions in run-time and then also a
"(*(dynlink(OBJ *)))()" function.  Hmm... and maybe an sdb() function...
