[rcr] String#split behaves odd

[Simon Strandgaard]

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

Perl's split() works as you described above. You just need to call it
in "list context":

@arr = split /\n/, "";
# ...

Try

@arr = split /\n/, -1;

Which I think should be defualt behavior.

Feeling odd is subjective. Could you tell me why you felt
String#split is "wrong"?
