Hi Andrea,

Could you measure the performance impact of function referencing.

<?php
$func =3D "strlen";
for ($i =3D 0; $i < 10000; $i++) {
    $func("hello");
}
?>

vs

<?php
$func =3D &strlen;
for ($i =3D 0; $i < 10000; $i++) {
    $func("hello");
}
?>

I don't like the "&" syntax a lot, but I understand that it's a compromise
between readability and implementation complication.

The patch probably misses support for "&self::foo", "&parent::foo",
"&static::foo".
It also may be improved using run_time cache (this is not important now).

Thanks. Dmitry.
