This is very serious. Walter and the rest always complain that C++ is very hard to understand, has a very long and verbose syntax and only "a few" can really master it. And look at that code. It's impossible to understand. One has to jump from one place to another, back and forth, wondering "Why that alias?" and so on. The nested depth of curly braces go beyond four and five sometimes. Oh, wait. But I can do "scope(exit) ..." and then I save myself one level.
So imagine if it takes all that effort to understand what it is written, how hard it should have been to write it. Probably it's the result of "this doesn't work, let's try this as a hack" and everything ends up being a huge hack. Please, please, please, look back at what you've done and think hard if it is really the right way to go. Everything seems overly complex by now. </just trying to help>
