That's disgustingly.... genius. I'm a bit jealous I didn't think 
of it myself!

One slight problem though: you couldn't call super() from a 
derived class, since the constructor wouldn't even exist due to 
the constraint.

You could just put the hard work in a protected helper function 
though and then child classes call it instead of the super 
ctor....
then you could do a mixin template that forwards to that to kinda 
automate this ctor too.

this is fairly usable!
