Oh, the other - bigger - objection to that is that epp uses file:open/2 and then the file_io_server functionality* to fetch parsed forms from the file. 

The reason why I mentioned read_file in this case was just because I used that to fetch the file and put it into a ram_file, and then making prim_file "ram_file-aware".

* Actually, the call is:

scan_toks(From, St) ->
    case io:scan_erl_form(St#epp.file, '', St#epp.location) of
         ….
    end.

where io:scan_erl_form/2 becomes an io_request to the file_io_server.
