Hi Thomas,
As I said in a mail early today, this bit of code below will work but
is not recommended. The collection classes in ROOT do not delete an object
in a list if the object is not in the heap.
However, the algorithm to detect if an object is on the heap or stack
is not guaranteed to work on all machines/systems or future versions
of compilers. That is why, we would like to discourage this kind of constructs.
