Hello,

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

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.
