I would be quite interested in an utility that could generate a single functor with multiple overloads from multiple functors.

It could be quite useful for example to visit a variant and all kinds of pattern matching.

I tried to implement it, using this [1] as a basis. But then I wanted to add Lambda and ResultOf support, and thus I realized the reflection mechanism could really help to figure out what argument_type should be.

Any ideas about how to implement that and make it work with ResultOf and Lambda?

Boost.Egg experimentally contains egg::overload. If interested, see: http://tinyurl.com/68luzd (It supports ResultOf and Lambda.) Regards, -- Shunsuke Sogame

Please check my overload library overload_26_3_2008.zip in boost vault. If the user interface is what you need then there is a good news: I've developed a new version customized for Dean dispatcher that uses boost.function instead of the simple home grown one included in the above file. What actually I have almost ready it's an extension of boost.function that we could call "Multi-signature boost.function" that does what you would expect from the name including assignement from a boost.function object. Code is still not public (sent only to Dean), but if you are interested I can drop you an email with the attachment. Regards Marco
