Hello all, Do you know of any N-paper, use case, example, etc I should consider for local functions? Now I have a basic implementation of Boost.LocalFunction so I am looking for examples to implement to test if the library supports all necessary functionalities and use cases. 1) I have found this N2511 (and I will also check the N-papers it cites): http://www.open-std.org/JTC1/sc22/wg21/docs/papers/2008/n2511.html 2) My original use case for local functions was a constant code block ("cb"): class c { void f(int x) { const int y = x; { BOOST_LOCAL_FUNCTION( (void) (cb0_code)( (const bound)((this)(&x)(&y)) ) ) { // Code compiled in const-correct context. assert(x == y); assert(x > 0); } BOOST_LOCAL_FUNCTION_END(cb0_code) cb0_code(); // Execute code now. } } }; 3) Also scope exit ("se") can be implemented using local functions and therefore considered as a use cases for local functions: class c { void f(int x) { const int y = x; BOOST_LOCAL_FUNCTION( (void) (se0_code)( (auto bound)((this)(&x)(&y)) ) ) { ... // Stuff to do at scope exit. } BOOST_LOCAL_FUNCTION_END(se0_code) // Destructor executes code when this object goes out of scope. struct se0_resource { void ~se0_resource() { se0_code(); } } se0_object; } }; Where `auto bound` binds the variables in scope keeping their original const-qualifiers (e.g., `y` is bound as `const&` while `x` is bound as non-const `&`). Instead, `const bound` forces a const bound and `bound` forces a non-cost bound (e.g., using `(bound)((&y))` would have given a compile-time error because `y` is of const type so it cannot be bound as non-const, while using `(const bound)((&x))` would have been OK because any type can be promoted to be const as usual in C++). -- Lorenzo
