Do you ask about alias this or about it multiple usage.
Multiple usage is similar to single, but multiple:)
Just an FYI, bearophile is very knowledgeable about D and one of
the oldest community members, he holds the record for most bugs

this." As others mention kind of like "why would you want to use
multiple inheritance."
