which make the use of quite possibly the most error-inclined characteristics of C++ redundant, to make sure that they are often banned (in our list of rules).

This could generate too many Wrong positives in certain code bases; In that case, flag only switches that take care of most although not all conditions

By no means allow for an mistake to be described from the destructor, a useful resource deallocation operate (e.g., operator delete), or perhaps a swap function working with toss. It is almost impossible to write handy code if these operations can fail, and perhaps if one thing does go wrong it nearly never makes any perception to retry.
