As far as we know, there are no file operations inside the Lua
core.  (It uses sprintf, which is defined in stdio.h, but this is
not a real file operation.) In the other libraries, we try to keep
file manipulation to a minimum (print in baselib, debug in debug,
and loadfile/panic in auxlib.c; string.format makes heavy use of
sprintf, but does not use files). String operations we do use without
restrictions, as it is easy to implement them in C whenever necessary.
