Well, I'm not following you here. And in fact I fully agree with Sam 
(magpiebrain): I rather trust users to know what they are doing (and 
even more so in open source where everybody can see what is going on in 
the inside anyway). And if there is one thing that I've learned from 
creation and usage of frameworks, then that the places where the 
designer thinks that the user will change something (template & hook) 
are usually not the same places where users would like to (we had a 
couple of these, e.g. check archives for PersistentField and nested fields).

For internal stuff, then you're probably right though I guess a decent 
static code checker can find these too. As for the GC, well, I don't 
have enough knowledge about the internals of the VM to understand how 
the final keyword on a local variable would help the GC throwing 
variable values away earlier.
