after spending some time with the shootout i came to the conclusion that 
this might be intentional.
it could just have been me, of course.

there is a file:read/2 and file:write/2. they are both used for raw io. 
they are currently of limited use since it is not possible to use them 
with stdin/stdout/stderr. i suggest that it would be better to add this 
possibility (stdin/stdout/stderr), that to ask for a new bif.
imho.
