parse error - of all reserved words, only "namespace" and "import" are
allowed as class names in my patch

The only reason for me is that "use" implies some kind of autoloading,
as I suggested in one of my other mails.  This gets into parsing
semantics, something I'm not interested in doing.  If the folks go with
"use" that is fine, but for me personally not the best solution, which
is why I put hours into making this patch.

However, no matter what I definitely would like to see code written for
PHP 5.2 and earlier that uses "import" or "namespace" as class names or
functions continue to work in PHP 5.3.  "namespace" is used commonly for
XML information (for obvious reasons), and import is a very common idea,
as already stated.
