Comment (by nomeata):

 > If you want to count how many times a function is entered, why not just
 put a ticky counter at the start of the function's code?

 The problem is that I need to count each dynamic instance separately. So I
 need a separate counter for each allocated closure, so the only place it
 can go is inside the closer as another non-pointer argument.

 (For static functions, things are easier of course.)
