Dart 1.0

Dart released 1.0, but it looks like some political gesture, it seems having nothing to do with the quality of the system.
There are still many basic unresolved problems, like mirror, await etc.
Essentially certain power user cannot use Dart at this level of quality.
Also editor sometimes causing suppressing internal error, and showing bad error messages.
Anyway, they would have needed to show some progress for public, that would be the only the reason for they have released 1.0.

Also the last minutes announcement of deprecation web-component and replacing it by unproven polymer is also nonsenses move.
If it is experimental nature, it is better to avoid pushing such technology. This also would have come from political decision to provide some sort of solution to support component based web development which dart supposed to address. But like JavaScript does not provide such framework, Dart actually does not have to provide such 'solution'. It doesn't have to be a part of Dart release at all.

Since Dart is new language, it may take sometime to understand the best way to utilize new language features for component based web developments.
These thing may be delegated to communities, and wait to see emerging new solutions.

Also in general, if we develop with JavaScript, we don't see any fragment of HTML. So such focus on HTML file on Polymer looks very much old fashioned approach.
It will be an obstacle for utilizing full language capabilities to design component based library.

So I feel a lot of questionable thing for Dart right now.
But if I wait Dart 2.0, it may be something I expected as 1.0.
So just I may need to wait another year to mature.

At least, if Dart does not provide proper synchronization feature for server side application, it seems a waste of time to develop something on server side right now.
