What is your conceptual level? You haven't described what it 
does, and does not do. But yes, frameworks need that allow 
"scripting" in some shape or form (compiled or not) has to hide 
internal structures and intricacies and provide some convenience.

However, you write your own from scratch you can often times 
build the marking into an existing pass, so you get it for free. 
Not uncommon for people who write code that modify graphs.

There is a big difference between writing a dedicated collector 
for a dedicated graph, and a general ownership mechanism for the 
whole program.
