Speed of Lisp numerical code

[macrakis@harvard.ARPA (Stavros Macrakis)]

WHEREAS it has become increasingly obvious that those discussing this
  issue on this list are unwilling to read each others' contributions
  carefully; and in particular
WHEREAS some persist in confusing a language design with its existing
  implementations and with its potential implementations; and 
WHEREAS Lisp advocates especially (on this list; on others, it's C or
  Pascal or Ada or APL advocates) fail to see weak points in their own
  systems and strong points in others'; and
WHEREAS it is likely that all those not participating in the discussion
  and most of those who are, are tired of it;

NOW THEREFORE, I hereby withdraw from the discussion of numerical
  efficiency in Lisp and
DO DECLINE to rebut comments on my earlier contributions while
  continuing to maintain their soundness.

NONETHELESS I am willing to receive and will study any substantive
  contributions to this question, such as documented benchmarks.
