I think you forget basic fact: XML is ugly _bacause_ it was designed
to be a markup language.  Being a markup language language means
that "ordinary text" goes unquated, but the extras are more heavy.
Normal Lisp reader requires too much quotes for ordinary text.
If modify reader to treat parenthesis, comma and colon as text
characters then you will end up with a variation of XML.  While
using lighweight variant of XML makes sense you end up rewirting
software and retraing people.  Both have nontrivial costs.

BTW: Sorry, given such a nice flame war I could not resist to
take part...
