-Returns an array of substrings of +self+
-that are the result of splitting +self+
-at each occurrence of the given field separator +field_sep+.
-
-When +field_sep+ is <tt>$;</tt>:
-
-- If <tt>$;</tt> is +nil+ (its default value),
-  the split occurs just as if +field_sep+ were given as a space character
-  (see below).
-
-- If <tt>$;</tt> is a string,
-  the split occurs just as if +field_sep+ were given as that string
-  (see below).
-
-When +field_sep+ is <tt>' '</tt> and +limit+ is +0+ (its default value),
-the split occurs at each sequence of whitespace:
-
-  'abc def ghi'.split(' ')         => ["abc", "def", "ghi"]
-  "abc \n\tdef\t\n  ghi".split(' ') # => ["abc", "def", "ghi"]
-  'abc  def   ghi'.split(' ')      => ["abc", "def", "ghi"]
-  ''.split(' ')                    => []
-
-When +field_sep+ is a string different from <tt>' '</tt>
-and +limit+ is +0+,
-the split occurs at each occurrence of +field_sep+;
-trailing empty substrings are not returned:
-
-  'abracadabra'.split('ab')  => ["", "racad", "ra"]
-  'aaabcdaaa'.split('a')     => ["", "", "", "bcd"]
-  ''.split('a')              => []
-  '3.14159'.split('1')       => ["3.", "4", "59"]
-  '!@#$%^$&*($)_+'.split('$') # => ["!@#", "%^", "&*(", ")_+"]
-  'тест'.split('т')          => ["", "ес"]
-  'こんにちは'.split('に')     => ["こん", "ちは"]
-
-When +field_sep+ is a Regexp and +limit+ is +0+,
-the split occurs at each occurrence of a match;
-trailing empty substrings are not returned:
-
-  'abracadabra'.split(/ab/) # => ["", "racad", "ra"]
-  'aaabcdaaa'.split(/a/)   => ["", "", "", "bcd"]
-  'aaabcdaaa'.split(//)    => ["a", "a", "a", "b", "c", "d", "a", "a", "a"]
-  '1 + 1 == 2'.split(/\W+/) # => ["1", "1", "2"]
-
-If the \Regexp contains groups, their matches are also included
-in the returned array:
-
-  '1:2:3'.split(/(:)()()/, 2) # => ["1", ":", "", "", "2:3"]
-
-As seen above, if +limit+ is +0+,
-trailing empty substrings are not returned:
-
-  'aaabcdaaa'.split('a')   => ["", "", "", "bcd"]
-
-If +limit+ is positive integer +n+, no more than <tt>n - 1-</tt>
-splits occur, so that at most +n+ substrings are returned,
-and trailing empty substrings are included:
-
-  'aaabcdaaa'.split('a', 1) # => ["aaabcdaaa"]
-  'aaabcdaaa'.split('a', 2) # => ["", "aabcdaaa"]
-  'aaabcdaaa'.split('a', 5) # => ["", "", "", "bcd", "aa"]
-  'aaabcdaaa'.split('a', 7) # => ["", "", "", "bcd", "", "", ""]
-  'aaabcdaaa'.split('a', 8) # => ["", "", "", "bcd", "", "", ""]
-
-Note that if +field_sep+ is a \Regexp containing groups,
-their matches are in the returned array, but do not count toward the limit.
-
-If +limit+ is negative, it behaves the same as if +limit+ was zero,
-meaning that there is no limit,
-and trailing empty substrings are included:
-
-  'aaabcdaaa'.split('a', -1) # => ["", "", "", "bcd", "", "", ""]
-
-If a block is given, it is called with each substring:
-
-  'abc def ghi'.split(' ') {|substring| p substring }
-
-Output:
-
-  "abc"
-  "def"
-  "ghi"
