D2 is in beta...?

I agree is() and __traits is quite messy, and I have quite some 
workarounds for various stuff in the combination of is() 
__traits(), alias, enum and templates - basically generic 
programming.

But I doubt many people here agree D2 is in beta and will allow 
breaking existing code in ways that changing the aforementioned 
features would do.
