We're talking about sandboxing, so preventing the sandboxed Python
interpreter written in embedded BF from accessing arbitrary files is the
whole point.  If you want to let a sandboxed program access a file, you
create some kind of managed handle outside the interpreter, and pass
that into the interpreter so the interpreted program can make a
constrained set of calls on it.  That's how Java applets work and it's
basically the opposite of Python's "consenting adults" approach which is
to let everything access everything.
