Great table, thanks! Is there any way to find out when features other than keywords were added? I'm currently trying to find (1) when ref() began returning 'Regexp' and (2) when class 'Regexp' was added, if that was more recent than (1). Both ref() and Scalar::Util::blessed() return 'Regexp' as of v5.20.2. The referenced 5.38 delta page contains a link to select earlier versions, but it doesn't seem to work; a "raptor not found" error is displayed.
