Epp does use (or at least used to use when it was written) the io module 
without any strangities. It uses the normal tokeniser straight out of 
the bag. That's why things are still . terminated things even with epp, 
and why you can't define a macro inside a function. (Like you can in "C").

This is definitely the cleanest solution, add a function which takes an 
already open file. There is one problem though and that is when you use 
-include. Breaks the style.
