Return value from local scope?

Question

Bumped into some code like this in our code base... which made me worried.

int foo(int a); // Forward declaration.

int baz() {
    int result = {
         i         


        

Answer 1

With C++11 you can get pretty close:

int foo(int a); // Forward declaration.

int baz() {
    int result = []{
         int a = dosomestuff();
         return foo(a);
    }() ? 0 : -1;
    return result;
}
