Yeah, C++ exceptions were originally so troubled that no sane 
person would use them, thus you did not get the culture where 
most code was designed for it and "C++ with no exceptions and no 
rtti" became a mantra... For exception handling to shine you need 
consistency backed by culture. It is probably the culture around 
languages like Java and Python that foster that.

(Most of std::C++ is optional, templated and inefficient... There 
is no consistent culture. Though they got some thing right with 
unique_ptr and new language features recently.)
