I would suggest you commenting on the bug report. It would be useful to both the reporter and a core developer who's gonna consider the report. Best regards, Vadim Belman

Roles are fundamentally broken?

er! Maybe somebody could explain clearly why things are the way they are now. I would be very thankful for such information. Perhaps I need a tectonic shift in my understanding of this area. But currently roles are the only thing which really disappoints me in the language design. Best regards, Vadim Belman

Slangs: extending package_declarator problem

es some extra work some of which is clearly not needed in my case; and some perhaps necessary but I don't understand it yet. Best regards, Vadim Belman

Tricks: class cloning

o know if there is a workaround for this? Basically, what I'm trying to achieve is could also be done by using a role as a template which could then be applied to the custom class. But roles has a few restrictions which would make them less flexible. Best regards, Vadim Belman

LEAVE/CATCH/return weirdness

n this miraculous phenomenon to .map. Any other code within LEAVE, including 'for' loop, makes the whole thing to work as expected. I'm strongly convinced that what is observed is a bug. But before reporting it I'd like to make sure that there is nothing about .map that I don't know about and that m
