c++ love it or hate it?

personalty, i love c++ whats your opinion on it?

Are there any C++ compilers that can trace use of objects so that objects that are not used after the function where they were new'd returns are allocated on stack instead of hogging up heap space and causing memory leaks if the programmer is sclerotic/careless/stoned?  (I am aware that one can use a portable alloca-based hack; I want a REAL-WORLD ENTERPRISE SOLUTION.)
