Hi guys, i was just wondering if some notification mechanism ( signal/slot alike ) was planned in perl 6, like they already are in glib and qt ?
I'm not exactly sure what you're looking for, since I'm not too familiar with qt or glib, but if you mean will there be a mechanism to register watcher subs that get called when things happen internally (such as when a method is defined or redefined, or a class changes, or something of the sort) then yes, we'll be doing that.
It solves a fairly thorny problem with making efficient specific solutions in the face of a general problem, so there'll be built-in facilities for it. (What it means for parrot, specifically, is that we can build call structures and code designed specifically for whatever is the current set of methods and class behaviours, knowing that if something changes we can just rebuild our stuff based on the new layout because we've got a notification method registered)
