Symbolics vs stock hardware

[Jeffrey Mark Siskind <Qobi@ZERMATT.LCS.MIT.EDU>]

    So, yes, curious as it may sound, the only thing that would make
    Symbolics machines useful to me into the indefinite future would be a
    high-quality Scheme implementation.  I wonder if any other customers
    consider this a priority?

Jonathan Rees has a Scheme compiler for the 3600. I have never used it
so I can't comment on its quality. Actually I would very much like
the plain 3600 Common Lisp compiler to support tail recursion (and
continuations as well --- though the latter would require some
extensions to the language.) Many times I have taken to writing loops
instead of tail recursive calls solely for performance reasons and
would like to be able to stop that practise.
