This isn't actually elaborate as it doesn't recognize tabs
or multiple whitespace. It is even longer than

  words = gets.split

With no argument or nil, String#split uses $; what normally
is nil, too. Then, split uses something like %r/[ \t\n\r\v\f]+/.

You may easily read whole lines; they shouldn't become too
long. Reading the first word before the user typed enter
would need to tweak terminal settings. Not worth the effort
in most cases.
