Usually if you're working with a console though the input stream won't

The blocking behaviour of `stdin` by default is fine. The issue is that
`readln` returns an empty string when `stdin` is empty/closed, which is
different from an empty line (which is just the line terminator).
Approaches that erase the difference with functions like `chomp` can't
tell them apart.
Cue "empty vs null" theme music..
