S-exprs are a degenerate case of XML

<s-exp>defun foo <s-exp>x</s-exp>
<s-exp>let <s-exp>y <s-exp>1+ x</s-exp></s-exp></s-exp>
<s-exp>format t "y = ~d" y</s-exp></s-exp>

If the general consensus here is that XML is absolute shit, and XML is equivalent to Sexp, then Sexp is also absolute shit, right?
