I think that here D is working according to its current specs.

On the other hand this topic was recently discussed and despite 
Andrei the consensus seems that such error situations should be 
found by the D compiler. There is an enhancement request on this, 
I like it, and Walter seems to like the idea.

Mixin templates are a relatively new feature and maybe that alias 
use case was not considered, or it was not regarded as important. 
What are your use cases of aliasing a mixing template?
