Robert Haschke 91f97ca401 smart_holder fixups (#3012) ... * Drop constraints on casting of std::shared_ptr std::shared_ptrs can be shared across python and C++ by design. * Correctly report casting error It is important to return an empty handle. Simply returning None, would skip the error handling in simple_collector / unpacking_collector, although a python exception is set. A function call would then be processed with a (wrong) None argument! * Return None for nullptr * Revert "Drop constraints on casting of std::shared_ptr" This reverts commit 7cf53ae8b4.		2021-05-28 06:35:50 -07:00
