What would also be useful, at least potentially, is some way to  
indicate what order hooks should be evaluated in.  Suppose that  
foo.module uses hook_form_alter() to add something to the node  
creation form.  In order to write a module that changes the default  
value of that addition, you need to have the module name come after  
'foo' in the alphabet (presumably in the local LOCALE, but perhaps by  
ASCII order).  It would be nice to be able to have:

function hook_depends() {
	return array('hook_form_alter' => array('foo', 'taxonomy'));

This would indicate that this module requires foo and taxonomy, and  
that hook_form_alter should be called after foo and taxonomy's have  
already been called.

If there is a cycle that gets established, you would fall back to the  
current sorting order.

Does this make sense?
