since macro expansion is post read-time this code:

(with-xml-syntax
  <foo <bar>>)

no longer works. the original with-xml-syntax function was meant to be
used in conjunction with arnesi's { read macro:

(read-from-string "{with-xml-syntax <foo <bar>>}")
==>
(WRITE-STRING "<foo><bar/></foo>" *YACLML-STREAM*)
