You should contact the maintainer of the library, Douglas Gregor, which I assume is the one taking those decisions.
Very well...thanks...
Given a number of articles on the web titled "Fast Delegates for C++" or similar, and how they're supposed to be better and faster than Boost.Function, I am curious if you were able to make progress on this matter?
Actually, the only reason they outperform boost::function is because boost::function adds in extra assembly code for a comparison check (to null, if true it throws an exception). If that is removed (perhaps by a policy, I certainly know that most of my function would never be empty, would even be nice if the function defaulted to an empty function if empty instead), then boost::function becomes even faster. I have actually started to take a liking to Boost.Variant for function callbacks (if I know what they can be), it inlines it and the function pointer call disappears. :)
