Additionally it can be used as a base for multimethod implementation.
This is much more interesting to me. Can you elaborate or give some sample code?
Then you might be interested in the multimethods discussion in a July 2010 thread: http://thread.gmane.org/gmane.comp.lib.boost.devel/206203 As shown elsewhere in that thread, there's multimethod code available already in the boost sandbox. That code: http://svn.boost.org/svn/boost/sandbox/variadic_templates/libs/composite_sto... is one example. Another, more complete example, is here: http://svn.boost.org/svn/boost/sandbox/variadic_templates/libs/composite_sto... The more complete example shows the method can be used both with virtual functions and discriminated unions, such as boost:: variant or that in: http://svn.boost.org/svn/boost/sandbox/variadic_templates/boost/composite_st... Unfortunately, the multimethod using the one_of_maybe discriminated union can be a compile-time hog (based on some simple tests I've run). I've no idea why :( HTH. -Larry
