Is there any interest in a library which facilitates the implementation and interconnection of objects using Boost.Signals? [snip]

* I'm wondering whether the choice of operators (operator(), >>=.,

=) used is appropriate or whether there are better alternatives.

Sounds cool. I'd probably prefer to use >> and/or << as operators, though, if for no other reason than they're already overloaded by iostreams, so as library users we're used to expecting that overload. >>= isn't similarly overloaded, so it's something of a surprise. operator() isn't bad either, but << or >> are better visually. I wonder if a different operator (maybe || ?) could be used to create trees? Or maybe that gets confusing. Your example would become: frame_rate >> ((video_generator >> differencer >> flipper >> analysis >> database >> display1) || display2); I think this is clearer than your proposed syntax: frame_rate >> (video_generator >> differencer >> flipper >> analysis >> database >> display1) >> display2; because the latter implies that display2 gets input from the parenthesized sequence in the middle, which isn't the case (if I understood it correctly). - James Jones Administrative Data Mgmt.
