Function parameter passed by reference with default value to null

   Hi,

   I would like to know if I am alone to be shoked by this :

== 8< ==
function foo(& $bar = null)
{
}

foo() ; // runs
foo(null) ; // raise an error
== >8 ==

   Why the default value to null for a reference is allowed ? Is it a
bug, a feature ?

   Thanks !
