I believe his macro has mechanisms for catching some variables in scope
(at least, ScopeExit had).

Something you would do with

struct local
     local(int j_) : j(j_) {}

     int operator()(int i)
         return i + j;

     int j;
local f(j);

could be written as something like

LOCAL_FUNCTION_BEGIN(f, (j), (int i))
    return i + j;

Surely you would agree the second form is quite more succint
