OK, now I understand what you are missing. An important part of the functionality of Boost.Local is to capture variables from the enclosing function. Some even argued that C++ will never have true local functions, because you still have to specify the names of the variables from the enclosing function that you want to capture.

Of course, if you don't need to capture any variable from the enclosing function, using Boost.Local will only make your code more ugly.
