[scope] Some random thoughts

Hi All,
Two observations from reading the docs.

Why do I need a condition in scope_exit when I have a scope_fail?

I recommend putting warning somewhere in the docs that while using scope
guards you may inadvertently read an object after move:

std::string checked(std::string name)
{
  scope::scope_exit g{[&]{
    std::clog << "checked " << name <<std::endl;
  }};

  validate(name);
  return name; // name becomes moved-from
}

Regards,
&rzej;
