thoughts to the new proposed language character of #dart:

IMO, I think the metadate feature is much right for a general language.  "metadata" should have its place in one modern language from the practices of the server languages. There are many requirements in this field if you have some experiences in the mainstream language(I mainly use Java):
1. we need some construct to configure our programms.
then we have xml, yaml, json...but as developer, we hope in-language construct, that can be helped by metadata.
2. we need some construc to express the structure or architure of our programms. maybe this is same to req#1.
is it better to add a new keyword to the language to implement this requirement?
3. we need some contract for restricting the our codes. maybe this is same to req#1.
is it better to add a new keyword to the language to implement this requirement?

the goodness of "metadata" is that, the "metadata" is not code itself, so it has a week effect to the programm in this context; but the "metadata" have a type itself(the current proposal is a vaule of type^_^), so it can expose a strong effect to the programm in this context(better than the comment).

Dartium should be the must toolkit for every #dart enthusiast. I use a piece of time to resolve the starting of the dartium on my new #Arch based machine. Cheers! The key here is to install 32bit libraries correctly. I write a note for Arch linux users' information here: https://gist.github.com/2377636.
