Re: [boost] Any real-world need for static_cast_iterator, const_cast_iterator, dynamic_cast_iterator?

Personally, I've had much use of a custom made match<Type>() adaptor (using the Boost.RangeEx pipe syntax), that performs a transform with dynamic_pointer_cast and then filters null results.

The idea would be to skip items that dynamic cast to NULL in the operator++() and operator--()? Except that I'm not sure how to detect the end of the container... ... sounds interesting... - Nigel
