Function parameter passed by reference with default value to null

[Lupus Michaelis <mickael+php@xxxxxxxxxxxx>]

  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 !
