object aMemoryLeak;

void someFunc()
{   throw (aMemoryLeak = new Exception("hello world!"));
}

Would the compiler warn about this or make the exception normally 
garbage collected?

I'm not sure, but perhaps an entirely different syntax would be 
in place for throwing a refcounted object, so there's no special 
casing. For example, could a throw statement without the new 
keyword mean a refcounted throw?
