However, there are many other Boost libraries that use a macro API to save the application writes from writing boiler-plate code
Most of them are there to emulate a now C++11 facility or even better actually pushed for the same C+11 facility.
With respect to other libraries, there is no other Boost library (and no other library in general at least that I know of) that allows you to write local functions while retaining statement syntax for the function definition.
The problem is that there is no need for C++ local function IMHO.
It is true that if you have C++11 lambdas you will probably use those over Boost.Local closures. However, if you need to write code that works on both C++11 and C++03 and performs like C++11 lambdas on C++11, Boost.Local helps you there.
C++03 is C++03, could be good for everybody if the C++11 bandwagon was jumped on by more people. Havign boost starting to provide C++11 based library could be the bootstrap C++11 require. Bootstrap that will ensure compiler vendors care about the new standard.
int max = 0; bool BOOST_LOCAL_FUNCTION_PARAMS(int x, const bind max) { return x< a; } BOOST_LOCAL_FUNCTION_NAME(small) small(10);
just using phoenix and/or lambda : int max = 0; auto small = _1 < max; local functions could be nice fi you have huge ones. One liners becomes nightmares and if you have a huge local function, make it a function.
