/*
* From a comment left by Traps on 09-Jul-2007 on the array_shift documentation
page:
* For those that may be trying to use array_shift() with an array containing
references
* (e.g. working with linked node trees), beware that array_shift() may not
work as you expect:
* it will return a *copy* of the first element of the array,
* and not the element itself, so your reference will be lost.
* The solution is to reference the first element before removing it with
array_shift():
