I agree with this as far as the "do what 5.10 does" is concerned. But dying is more than just subtly different from returning a count. :) I actually find that the best solution: scalar split in 5.12 and later will just die. This is acceptable because that feature has been deprecated for a long time and is now gone. But if you add "use 5.012" then you enable the *new* feature: split in scalar context returns the count but doesn't update @_. This may look surprisingly similar to the old feature, but it *is* different, and it doesn't work correctly on older Perl versions, so I don't know why it should not be disabled unless you ask for 5.012 or later.
