To me, the worst thing about C++ is the syntax. As someone who wrote a  
parser, I'm sure you know better than I where all the skeletons lie.

The second worst thing is the concept of "POD" vs. "non-POD" types. This  
seems expressly designed to violate the principle of least surprise.

Exceptions aren't even in the running. Exceptions are something that's  
present in almost every modern language - but most don't have syntax  
backtracking, or types both with and without initialization by default  
(and you can't add it to those that haven't got it without major surgery).

Programmer overhead, to me, is much more important than implementation  
overhead. Especially if the implementation overhead is only on the slow  
path.
