Well, perl5280delta mentions that "delete" can be used on key/value hash
slices, and also mentions new syntax for some regular expression stuff.
perl5260delta also mentions some syntax changes to regular expressions
and some modifications to how here-documents work.
perl5240delta mentions some new formatting support for printf and
sprintf, and again, more regular expression support.
I'm not entierly sure I understand what you're after.
