Subject: [rcr] String#split behaves odd

Maybe the return value of String#split is wrong.
If I invoke split on an empty string, then it
results in an empty Array (which I think is odd).

    ''.split(/\n/) #=> []


I would have expected this to happen:

    ''.split(/\n/) #=> [""]




For instance JavaScript has a good split.

alert("".split(/\n/).length);  // ->  1


Also Python has good split.

print "".split("\n");          #  ->  ['']


However Perl has a bad split.

$size = split(/\n/, "");
print "size is $size";         #  ->  0
