What Dart wants

I want to fall in love with a scripting language like I did back when there was Perl. These days there are so many!

I want something with a good IDE debugger. Not because I write a lot of bugs, but because I like to interact with my code as it runs. Javascript is looking better with ES5/strict and V8+node.js, but it still looks difficult to me (I like to understand the syntax in detail).

Probably I'm just being too picky.
