As just said by others, if you need it probably your module is 
too big and you have to split.

Moreover: you're the author of the module so you're supposed to 
know how it works and which members you should call or not. 
Anyway since they're private you can name them in particular way 
to remember yourself not to use them eg: int internal_A;
