Could it just take arguments by value and use boost::ref for references like the other function-like libraries?
I thought of it too, but I couldn't imagine the way to implement it. One would like to put "ref(arg)" into scope-exit arguments list, and I don't see the way to extract "arg" portion from this string to name the argument. -- Best regards, Andrey mailto:andysem@mail.ru
