Yes, it would be nice to have a "If you do this in C, here's how you do 
it in D" guide. It could be part of the tour, for sure. Just tag it 
intermediate.

In terms of arrays, they aren't much different in D than in C. Just with 
better checks for safety. In fact, you can use C arrays (T*) in D just 
fine, with the same syntax and problems.
