Here's a first draft for the docs:

Comments welcome.
What are the use-cases for such a beast?
Just the case that you have a bunch of functions (function pointers, function references, and monomorphic functors) with different names and you want to combine them into an API with a single overloaded function name. History: The idea was originally raised as a side discussion on the limitation that local functions cannot be polymorphic http://lists.boost.org/Archives/boost/2011/05/181501.php . No Boost.Local reviewer raised concerns on adding overloaded_function and the consensus was to potentially add it under Boost.Functional. However, my impression was that all reviewers saw this as a "nice to have" (so no object but not strong preference for addition either). I since then asked Boost.Functional authors (and Boosters in general) if there is any concern with adding this functionality but I didn't get much of a reply :( Do you have any concern? Thanks. --Lorenzo
