    ...  Rather, we are arguing a subject that I might call, in the
    recent style of SIGPLAN: "Uncontrolled extensibilty considered

Indeed, this argument seems very much like the "GOTO considered
harmfull" arguments to me.  A language without GOTO is a cripple,
despite any "elegance" you gain by removing it.  Whatever it is that
you propose to do to "control" the extensibility of Lisp can only harm
it.  Just like with GOTO, if you want a truely powerfull language, then
you have to leave in the parts that are capable of producing uglyness.
