I was thinking that you should replace the wrapper property in 
class_t with a more generic code_creators, of which one is the 
wrapper class (if needed). Call it 'classfilecreators' or something. 
Then to add things per class file, you simply adopt a custom text 
creator into it.

You'd need to be careful when using the single file writer as some 
items may duplicate. Of course, this is probably an end user problem.

I'll wait for your solution and use diff and patch in the meantime.
