I just answered this question in your thread "Re: "Hiding" the mixin 
keyword?" in d.D.learn.
For the people who don't want to go look it up:
-----
Looks like he hid the mixin() in a templated function call, using 
property syntax to remove the trailing ().
I'm pretty sure that means he can't support variables in the 
initializers, nor expressions containing variables.
It would seem these are quite important for a (runtime) string formatter 
though. ;)
