You can generate code on the fly as well, that is a common trick 
to create, for example, optimized ORMs, regular expression 
engines or image processing algorithms that are then compiled to 
native code with the JIT.

Runtime reflection, attribute processing, AST manipulation and 
bytecode generation can help a lot in meta-programming.

It isn't as easy as D's mixins, but it gets the job done.
