The idea is that one can regex-search for "^struct 
see_pre_extension_expr" and get to the right point of the source code; 
there's no need for other information like the fact that a struct is 
"Data structure IV".

It's fine if you do it the other way round.  That's the way it is done 
in most of GCC's source code.

I think the idea is that, at a superficial stage of code reading, you do 
not need variable names, and the declarations would only crowd the 
reader's mind.

I was not commenting on the concepts.

Thanks,
