So templated functions dont need to be inside a template block? You only 
need a template block when you want to group a bunch of stuff together into 
one template, so the whole lot can be created in one go?

Looks good, I should be able to learn a lot from that.

It's surprised me how very often, even with more advanced features, the D 
syntax seems to be exactly what you would expect it to be. A very good sign 
imo, it seems so intuative straight of the bat.
