A GCed language requires good stack escape analysis. Unless you expose it to the programmer for at least semi-manual MM, it is bound to have false negatives, where you pay for the allocation on the heap unnecessarily. I totally agree about std::string. I think C++ with the conventional libraries is actually an example of how to do manual MM badly.
