d245c52e0c Fix for bug #22367. 
Heads up - this will break syntactical compatiblity, return($foo) will
not work with functions that return references - return $foo should be used
instead.  It never worked well before, and caused all sorts of odd bugs.
It *might* be possible to support this specifically, albeit unlikely

a4c3b2ce80 Namespace patch. Big changes: 
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
	class X { ... }
	function bar { ... }
	var x = 1;
	const ZZ = 2;
}
3. Namespaced symbol access: $x = new foo::X; - etc.
For now, namespaces are case insensitive, just like classes.
Also, there can be no global class and namespace with the same name
(to avoid ambiguities in :: resolution).

__get/__set are not recursive, __call can be.

41e3f4f0c3 - Fix problem with debug_backtrace() reported by Stig. We weren't reporting 
- global function information because it wasn't available. We have to do
- an additional assignment per-function call so that it'll be available.
- Also don't define the global scope as function name _main_ but leave it
- empty so that frameworks like Pear can decide what they want to do.

7b68f5108a - Nuke delete(). It was a big mistake to introduce it and I finally 
- understand why Java didn't do so.
- If you still want to control destruction of your object then either make
- sure you kill all references or create a destruction method which you
- call yourself.

b55a20abf4 - Fix problem with scope's not changing correctly during method calls. 
- Reapply a tiny optimization to the allocator so that in non-debug mode
- we clean memory without detecting leaks.

68663bf96b - Revert patch which checks at run-time if you're allowed to assign 
- certain values by reference.
- We still need to find a solution for cases when this shouldn't be allowed
- as it might cause leaks.

7e5ec2d761 Initial support for built-in backtracing. 
There are still a few problems such as includes and calling other functions
from internal functions which aren't seen (will have to think if and how to
fix this).
Also the main scripts filename isn't available. Need to think about that.

	class MyClass {
		static $hello = "Hello, World\n";

		function Hello()
