io_lib:format/2. Not a BIF.

1> io_lib:format("~p", [{tuple}]).
[[123,["tuple"],125]]
2> lists:flatten(io_lib:format("~p", [{tuple}])).
"{tuple}"

If you're writing it to a file, you should just use the output iolist
directly (as shown in 1), because it will be more efficient. The
second example is just to show equivalence.
