Actually, I'll disagree with both of you. I think alias this is 
really about enabling implicit conversion to the type of alias 
this. And multiple implicit conversion is obviously useful.



Though speaking of template mixin, I think it would be kinda cool 
to be able to mixin a struct or maybe a .tupleof thingy; just 
treat a struct as if it was a mixin template.
