Yup. That''s because it was modeled after the split function in
Perl, which behaves exactly the same way.
Given the relative paucity[1] of Ruby documentation, familiarity with
Perl can be a good way to set your behavioral expectations. Of course,
if it''s something you can test (as opposed to a feature which might or
might not occur to you at all), that''s the best way to determine the
behavior.

[1] I did say "relative". There''s just a heckuva lot more info out there
about Perl. The Ruby situation is steadily improving, however, and the
Pickaxe book is a wondrous thing. :)
