I don't know how long this EuroOSCON net is going to stay up, so I'll be brief. I think we're having a new "class" sigil. Where we've been writing ::T, that will revert to meaning "an existing class T that we just might not see the declaration of for dynamic reasons". Instead, the new sigil is the cent sign, so ::T is now written ¢T instead.
In addition, it doesn't automatically bind to T like we were making ::T do, so you have to use it consistently: sub sametype (¢T $x, ¢T $y) {...} Within a larger scope, you can always alias, though: ::T := ¢T; Larry
