I used m4 to that effect to generate some set-like and map-like strongly-typed classes for a j2me project. Must have been 15 years ago.

For C and C++ in particular, X macros are another technique that can be used to generate boilerplate nicely. I use that quite a bit to this day, even in C++, where it's not needed as much due to templates.
