I wanted to address your post in the reddit discussion regarding the issue  
of operator overloads not being virtual:

"This non-issue has been discussed in the D newsgroup. You can implement  
virtuals on top of non-virtuals efficiently, but not vice versa."

I've found some very real problems with that, when implementing operator  
overloads in dcollections.  It's forced me to use the (yet to be  
deprecated) opXXX forms.  Specifically, you cannot use covariance with  
templated functions without repeating the entire implementation in the  
derived class.  Also, let's not forget, templates can't be used in  
interfaces, which means no operator overloading in interfaces.
