$ ri String#split
str.split(pattern=$;, [limit])
  If the limit parameter is omitted, trailing null fields are
     suppressed. If limit is a positive number, at most that number of
     fields will be returned (if limit is 1, the entire string is
     returned as the only entry in an array). If negative, there is no
     limit to the number of fields returned, and trailing null fields
     are not suppressed.
