Please let's keep this to the point. There are no const_casts in the 
proposed Boost Exception library. If you think that the dynamic_cast can be 
avoided, I'm very much interested to hear how. If you think the need for 
dynamic_cast is a result of poor library design, I'm very much interested to 
hear about any improvement ideas.
