Hmmmm.  So a typical use would look like the following....

(define (js-string zzz)
#{
<script>
<!--
function qs(el)
   {if (window.RegExp && window.encodeURIComponent)
        {var qe=encodeURIComponent(document.f.q.value);
         if (el.href.indexOf("q=")!=-1)
            {el.href=el.href.replace(new RegExp("q=[^&$]*"),"q="+qe);}
         else
            {el.href+="&q="+qe;}}return 1;}
// --> #[zzz
          #]
</script>
#}
)

The advantage is that the tokens indicating the beginning/end of string 
status always
start with the # character. Yes, I think that is nicer. We then think 
of #{ #} #[ #] as tokens
although #[ and #} denote the ends of strings, while   #{ and #] denote 
the beginnings
of strings in different contexts...
