Oh yeah, that can be done too.

Here's an example:
http://arsdnet.net/dcode/autoimpl.d

The mixin template is implemented by a helper function, which 
loops over the interface methods and builds a code string for it. 
It doesn't handle complex cases, like a setter without a getter, 
but it is a start.

The pragma(msg) in there shows you the generated code when it 
compiles, which can help debugging or just show you what's going 
on, of course you can remove that when you're happy with it.
