I liked the fundamental idea that all curlies are a sort of closure and the control flow keywords simply become funny-looking exceptions. I bet we will find ways to take advantage of this - be it some new often-used idiom or simply for golfing.
:-) Overall I must say the whole deal is looking very Perlish, though pretty different. Getting used to it will be interesting.
The only part I don't really much like is the way properties and type hints clutter up what used to be the simplest and most intuitive part in the language - the mys. We'll see how people come to deal with it. In my current state (though this may well change after a while of composing Perl 6 code) I'd hate the idea of every my under the sun having a type declaration and every other one having a half dozen properties. But we'll see how mandatory these features will feel in two years.
Makeshifts last the longest.
