FWIW, a lot of people I try and get in to D complain about the 
template syntax. "What're all those exclamation marks 
everywhere??!!" - Every. Single. Time. And as soon as you see 
__traits code anywhere you can say good bye to any aesthetic 
pleasures. There're things in every language you just have to get 
used to looking at and at some point things just start to look 
nice. After a while I didn't even think objective-c bracket hell 
was too bad :p
