[wp-hackers] PHP Coding Practices

[Dave Grijalva]

That's not really true.  I'm pretty sure you can foreach a PHP4 array.  It's
been a while since I coded in 4, but I think it returns the objects
properties.  In either case, it seems foolish to include code that will
become a problem in the future, no matter how remote.  Plus, people who are
running on 5 and want to take advantage of it should be able to.  Backwards
compatibility is great, but forwards compatibility is a no brainer.
