Language specs aren't a good resource for learning. I'm also not 
trying random things. I have a clear idea of what I want to do, 
and I'm in the process of learning how D does its thing, and 
whether its a reasonable choice for me. I've found an example 
which is simplified and closely related to something I want to 
do. It fails and the compiler errors aren't helpful. I've posted 
it here and gotten detailed responses from people who know what's 
going on. Extremely useful. Thanks in advance for your patience, 
since I will invariably be posting more of the same.
