I think the final agreement was the need for some kind of code marking system, which I tried to implement as best as I could. It gives very good performances while tracing (advantage of static tracing), has a very very minimal performance and binary size impact when disabled (advantage of dynamic tracing) and it can be activated dynamically (advantage of dynamic tracing).
