I'm not sure what you mean.

This is true and it may not even be rare: turning C++11 on or off 
is doing it for some Qt classes.

But there is another issue that will make me revisit their 
semantics anyway, it's that C++ structs and classes shouldn't be 
garbage collected because they weren't made with GC in mind and 
might have weak refs. So unless someone has a better solution C++ 
classes will go back to manual memory management, and the plan is 
while changing class and "new"'s semantics to also make all C++ 
classes values.
