I didn't delve into this point and you should check my assumptions.
Up until now, I didn't have any problem treating a circulator as a handle, operating any functions of the handle on it. There suppose be a direct conversion from a circulator to a handle but you should check the declarations.
For the other way, I assume that a circulator is just a list of handles. So, if want to know the location of a handle in a list, you should iterate the list from the beginning. Then, no directly there.

That works fine for me, and I'm nor sure that you need more.
