I don't agree with implementing things just because we can. There has to be a 
good case for it. I cannot see a case for catching ints, strings, etc. My 
understanding is that this is more or less acknowledged by the C++ community, 
and std::exceptions are used.

Having dealt with mangling issues for decades, I'm not overly concerned about it.
