Rvalue references were introduced for move semantics to avoid copies but are also used to manage the lifetime of temporary objects.
The pre-C++11 feature for extending temporary object lifetimes does not work correctly with rvalue references, necessitating a custom macro to create a value or reference based on expression type.
Standard accessor methods returning a const lvalue reference incorrectly bind to rvalues, losing critical lifetime information and leading to dangling references.
A proposed language fix using pragmas would introduce new, safer reference binding rules to prevent short-lived rvalues from binding to long-lived lvalue references.
Use custom macros to manage variable lifetimes, guard member accessors, and implement a correct ternary operator to work around the language's flawed binding rules.
The best way to manage the growing complexity of C++ is to establish strong internal coding guidelines and use custom libraries to standardize code patterns.
