I took a look at the pdf, but couldn't see how the AST macros could come
close to the kinds of things that are possible (but difficult) with 
mixins. Is there more information somewhere?

Jacob, I can see how your proposed syntax would make simple mixins 
easier and clearer, but how would it do something more complex?

For example taking a classname and a bunch of field types and names, and 
turning it into a class definition complete with constructor from field 
values, constructor from an input stream, a method to write to an output 
stream, and const getters. Or maybe std.typecons.AutoImplement.
