1) I'd propose to never implement BOOST_SCOPE_EXIT using lambdas. There is no advantage for the user in the lambda implementation
What about 1) compile-time speed 2) run-time efficiency
Aren't both of those better with lambdas?
Bases on my LocalFunction benchmarking: https://svn.boost.org/svn/boost/trunk/libs/local_function/doc/html/boost_loc...
I'd expect ScopeExit with lambdas to be only marginally if at all faster than ScopeExit without lambas for both compile and run time. But I must confess that I didn't directly benchmark ScopeExit with and without lambdas so I could be mistaken.
Doesn't the use of C++11 remove all the ugly virtual stuff?
No, the "virtual stuff" is used by LocalFuncttion* to pass local classes as template parameters but it is not required at all by ScopeExit. (*) Note: A static member function and a static_cast were used at the end instead of the "virtual stuff" because faster. On C++11, neither of this trick is needed because local classes can be passed as template parameters but not because of lambdas which are not used by LocalFunction.
