I understand and to a good extent agree with the sentiment.

However, right now GSoC with student proposals to attract and review, an 
undergoing Phobos proposal review, one or a couple more waiting in the 
queue, good progress in core areas (64 bit stabilization, rigorous 
deterministic destruction, important bug fixes, and to follow the 
immutability subsystem and shared libraries) I can't stop feeling many 
of such discussions do more harm than good. There's always a better way 
to express a frequent idiom, and we may as well adopt one later. But 
this is the time to act, and there's plenty to act on.

Let's focus on getting real work done. This is the D Summer of Code. :o)
