It looks like the split is counting three elements in the list
($a, undef, undef, $d, $e) and splitting the string into four pieces.

($a)    = 'a';
(undef) = 'b';
(undef) = 'c';
($d)    = 'd,e,f';
($e)    = undef;


I'd say it's a bug.


MacPerl 5.2.0r4 appears to be based on 5.004, not 5.004_04.  :/
