I don't see any need to change the defaults as how type objects or their definedness is implementet. Changing for example the params to mean Int:D by default when one writes Int is something you have to explain a lot. And in fact it is a lie. There are some basic rules about Perl 6 like TIMTOWTDI and DRY, but there is also a rule about "All is fair if you predeclare". But if I don't predeclare that I mean Int:D by writing Int, then the compiler is not allowed to change the meaning of what I wrote.
That said, if there was a change that justifies breaking a lot of stuff, I'm for it. But here it is certainly not the case. -- Tobias
