When you decide to implement code-generation, you have to make some 
decisions.

* Do you intend the generated code to be read and debugged by human beings?

* Do you intend the generated code to be modified?

Most code generators don't have clear answers to these questions. They 
want to have it both ways: allow programmers to read and modify the 
generated code so that there's an "escape hatch" when the functionality 
or performance of the source language proves inadequate to the task, but 
without taking the consequences in terms of producing readable and 
maintainable output.
