Hi all. I was curious to see if there is or will be support for the use of the visitor pattern with boost::any? I think it would be very useful. I thought I had read that there was an experimental boost::any visitor at some point, but I couldn't find it.

Please let me know.

Thanks.

I've done such a thing using a defined set of types and an if..else if chain, using the type() member of any and typeid() to switch on type...however, I *only* did this because it was before Boost.Variant was available. If you have some strict set of types that you're looking for, Boost.Variant would be a better option. Stuart Dootson
