I am not reading the php mailing lists, so I may ask for a
frequently requested feature or i may cause a flame war,
but I would really like to have a way that allows me to
define pseudo-tags and bind them to functions.

For example, if I had a function that created a HTML-Table
from a database query called dumptable(), I would like
to be able to bind dumptable() to a pseudo-tag of an arbitrary name.

If I chose for example to bind dumptable() to SQLTABLE and
its parameter $query to an attribute "QUERY=" of SQLTABLE, I want
to be able to write

<SQLTABLE QUERY="select ...">...</SQLTABLE> instead of

<?php dumptable("select ...") ?>

How far-fetched is such an idea?
