Detailed Description

Functor to run some code when this variable goes out of scope.

Useful for performing some action after a function returns, for example:

void sayHiOnExit() {
    OnScopeExit se { []() -> void {
         std::cout << "Hello world!\n";
    }};
    // function body etc etc etc
}

Will print "Hello world" after the function body has run.

Lifetime concerns apply here, be very very careful.
