Detailed Description

template<typename T>
class pyobject_deleter< T >

Used as a std::shared_ptr deleter (second argument) to overload delete ptr with Py_DECREF(ptr).

This allows data to be shared between C++ and Python that will be deleted when both reference counts reach zero.

The effective reference count is a lexicographical tuple of (Python reference count, C++ reference count), where the Python reference count is the most significant digit. A single Python reference count is held for all C++ references to the object.
