Just an FYI, bearophile is very knowledgeable about D and one of 
the oldest community members, he holds the record for most bugs 
opened.

This doesn't mean he knows everything, but it certainly makes it 
clear he was asking, "why would you want to use multiple alias 
this." As others mention kind of like "why would you want to use 
multiple inheritance."
