      Hello,

Sorry, I didn't have much time to write this email sooner.

That's a bit restricting. I could really use a overloaded_function
that received a MPL or Fusion
sequence as well.
Why do you need to use MPL and Fusion sequences? What's the use case?
This would happen if the overloads are computed
by metaprogramming instead of being hard-coded
into the source.
Yes. That's exactly the case. I'm writing a Java Binding library, and
all I need to pass at runtime is three variables to create an overload
set that is mapped to functions in Java. And at compile time I need
to specify all the function overloads. Since it is not necessary, I
don't want the user to create all function objects seperately, since
their constructions are all the same. I need to pass just a sequence
of function prototypes and the three variables I mentioned and I can
just return a boost.overloadedfunction constructed by metaprogramming.
