Let see, what else. These could, most likely, have been implemented 
using AST macros:

* scope
* foreach
* for
* inlining delegates. I think the current solution to pass a 
delegate/lambda as an alias parameter is a bit weird

One of my favorites that is not already in the language is implementing 
database queries:

Person.where(e => e.name == "John");

Will be translate to the following SQL:

select * from person where name = 'John'

Another one is the property shortcut, see the example for attribute 
macros: http://wiki.dlang.org/DIP50#Attribute_macros
