Recently, I asked my hosting provider when they are going to switch to
PHP5. They replied that it will not happen any time soon, since they
will install PHP5 only on new servers. Their reasoning was simple: PHP5
will inevitably break some old scripts, and it's just not worh all the
trouble. Such attitude is common, and it totally makes sence from a
business perspective. That begs the question, why PHP developers are so
worried about maintaining BC? There is a simple alternative:

<?php //parse this with mod_php4
function class_method($var){ }
?>
<?php5 //parse this with mod_php5
class clazz implements Something{
function method($var) {
}
}
?>

So what's the reasoning behind BC maintenanse?
