Hello folks!

I'm sure this question has been asked many times but here is it anyway:

How can I determine whether an object has been instantiated by allocating
heap space ("new") or whether it is global/static/automatic or even a member
of an other object.
In other words: does a particular object have to be destroyed by calling
"delete" or not. 
Is there a proper (and portable) way to do determine that or is there a
proposal for the new C++ standard to achieve this functionality?
If not, what's about a function "is_dynamic(x)" (where 'x' is a pointer to
an object) that returns 1 for dynamically allocated objects and 0 in all
other cases.

I often came across situations where this information would have been very
useful. 

Thank you for your attention!
