You can just not give them names.

For names that won't be used, it doesn't matter what the name is. In 
some languages, the single underscore symbol is reserved for names that 
won't be used. So when porting to D, perhaps there is the case where you 
might feel they need other non-standard names.

However, in this case, D does not require names, so it's a moot point.
