Multiple values for R4RS.

[Guillermo J. Rozas <jinx@hpesogg.hp.com>]

    CL's handling of "extra" values is distasteful to me, because it makes
    the standard behavior complicated; I think that values should be
    discarded only when that is explicitly stated by the code.  This is
    not to say that I would be extremely upset should such a semantics be
    adopted, because I would just avoid using "truncation".  But on
    aesthetic grounds I would prefer something simpler.

I don't object to this position.  I object to trying to force this
position down my throat.
