i concur.

i would even accept if io.lines() raised an error if called with a
file that wasn't opened in text mode.

of course, i much prefer the contract to be clearly stated "due to the
underlying old C implementation, embedded control characters can make
it return wrong results.  if you need to read binary data, use
file:read()"
