Which is the reason one should use spaces.

Because that requires buffering, something that affects speed. Are you 
willing to sacrifice the speed for _all_ usecases just for the _few_ 
that would actually benefit from the eof()? I myself have seldomly found 
the need for eof() - but permanently used the generator style of 
line-producing files implement.

Considering your own repeated remarks about "I'd only use ruby if it 
wasn't slower than Python", I'd think you could value that.

And you have been shown clear, concise solutions to your problem. Which 
add the benefit of working in general stream scenarios, not only with 
actual files. Granted, they aren't part of the stdlib - but then, lots 
of things aren't.
