They probably used an if.

But I think it's not about that. If D didn't have the possibility to 
define case range statements, it would be better. Now there's a 
possibility to do that, but with an ugly syntax (you'll find out when 
this newsgroup will receive about one or two complaints about this each 
month, not to mention there were already a lot of complaints). You can 
find other "ugly" things by looking at repetitive mails to this newsgroup.

Also, there's a limitation of just 256 cases. What's that? Where that 
limitation come from? That looks week.
