Hey Jan - First off, let me say: excellent idea! Several times I've wanted just such a class, and I would be happy to see this added to Boost.
I have a few suggestions/things to consider: 1) Instead of "operator bool", use the unspecified-bool-type discussed elsewhere on this list; it's safer. 2) I'm not sure that the choice of the name is ideal. OTOH, I can't think of a better one... 3) I'd like to see a general solution for this problem using real (late-bound) function objects as well, if you know what I mean. This would be a lot harder, though, so maybe it should be put on a wish-list. Have you given any thought to this approach? Regardless of the above (minor) comments, I'd like to see this class in Boost. -Steve _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
