RFC: Namespace declaration with leading backslash

Hi, I was looking at namespaces in PHP 5.3, http://de3.php.net/manual/en/language.namespaces.definition.php. There I found myself wondering why a leading backslash in namespace declaration is not allowed. For example: <?php namespace \A { echo "in namespace \\A\n"; } ?> I image that a trailing backslash could become a common programming error, especially as it is required when refering to symbols with their absolute name. <?php namespace A {

    const FOO = "This is FOO in namespace \\A\n";

} namespace B {

    echo \A\FOO;

} ?> Best regards, Bernhard Schmalhofer
