Error: template instance `Reflect!(type)` cannot use local `type` 
as parameter to non-global template `Reflect(Ts...)()`

mixin(`import `~moduleName!(T)~`;`);	
mixin(`alias X = T.`~name~`;`);			
super.Reflect!(X);

I realize X is local but I'm trying to figure out why it can't be 
passed to a "non-global" template.
