Or you can use Lisp, call your boilerplate generator a macro and get rid of any boilerplate and never again have any problems with modifying any duplicate piece

Or you can use Lisp, call your boilerplate generator a macro and get rid of any boilerplate and never again have any problems with modifying any duplicate pieces of code. Sigh... every time I see people generating any code (say through external tool or through IDE) I am always thinking how this could be a simple macro in any Lisp language.
