Re: CT info about class' children
Also, this whole thing is not only about RT registration, it may be used differently. The next usage that comes to mind after RT is validating proper inheritance. E.g. Some root class wants it's subclasses to always have a default ctor available, which again can be verified in CT.

Re: CT info about class' children
rtInfo through attributes implemented. Jacob, have i done it the way you wanted? https://github.com/D-Programming-Language/druntime/pull/775#issuecomment-41278520

Re: CT info about class' children
Ok, i've added a pull request to be discussed. It expands RTInfo capability as Jacob suggested. What do you think? https://github.com/D-Programming-Language/druntime/pull/775

This template will be instantiated with all user defined types * For each type that is a class, check all it's parents via __traits * If a parent is matching what you're looking for then you found a child -- /Jacob Carlborg
