Ricardo is pushing for smart match changes.
This sort of change should be important to all Perl users. We already have two versions of smart match out there so you have to be careful with your Perl versions. This would add a third. I don't think these changes are in the interests of most users, and unless ordinary users pay attention, they'll get whatever p5p decides to give them.
Jesse Vincent proposed moving all smart match changes out to pragmas so you could know which one you would get. He also suggested that new features come in as pragmas before they make it into core.
