This would work if you were using something like Boost.Fusion in the
background where most of the processing is done at compile time.
However I believe the OP was looking for a solution at runtime, which
pretty hard to achieve if you're going to rely on RTTI.

I'm looking for a similar solution, but more towards improving
http://dispatcher.sourceforge.net/ to be able to support multiple
function signatures in a single dispatcher instance. I think I've got
a way to accomplish that with Boost.Fusion, but I doubt this same
approach you propose will work for runtime determination.

Unless I'm missing something, in which case please enlighten me.

Thanks!
