Sloppy's Journal: Circular dependencies in three languages 1

Journal by Sloppy

Here are six files for ya, showing a problem in 3 different scripting languages. What will they do?
--------- test1.php:
<?php
require 'test2.php';

define('SOMECONSTANT','hello world');

function foo() {
                return SOMECONSTANT;
}

echo foo(); echo "\n";

--------- test2.php:
<?php
require_once 'test1.php';

echo foo(); echo "\n";
--------- test1.py:
#!/usr/bin/python
import test2

SOMECONSTANT='hello world'

def foo():
                return SOMECONSTANT

print foo()
--------- test2.py:
#!/usr/bin/python
import test1

print test1.foo()
--------- test1.rb:
#!/usr/bin/ruby
require 'test2.rb'

SOMECONSTANT='hello world'

def foo
                SOMECONSTANT
end

puts foo()
--------- test2.rb:
#!/usr/bin/ruby
require 'test1.rb'

puts foo()
---------
Ok, scriptfiends, predict the output of these three commands:
php -q -f test1.php
python test1.py
ruby test1.rb

and then do some pasting and try it out. Match your predictions?

The PHP one bit me pretty hard today.
