I wouldn't put it in production code that is (I mean some normal payed project)
And why exactly?
Plus, it's still in the alpha stage, not even feature-complete, not to say about the real, in-use testing. :roll:

no he had problems with exceptions, he did not want an alternative exception handling system
That's true. Not that I wouldn't want, but such things must be incorporated into project from the very start. It would require too many changes now. Not to mention that I use the Vampyre Imaging library that itself uses exceptions to report errors.
