No, this issue doesn't block me from using D. I'm asking because 
I encountered with a few things (like this one), which seems like 
they're a bit "unfinished".
For example:
http://forum.dlang.org/post/mailman.1463.1361561853.22503.digitalmars-d-learn@puremagic.com : "Don't use 'in', because it doesn't mean what it seems to mean, and it's not correctly implemented at the moment."
http://forum.dlang.org/post/lgqcjiuigsseoazirkor@forum.dlang.org 
- "cast `shared` away. yes, this is how you supposed to use it 
now: cast it away."

Reading topics like these doesn't add confidence. But don't get 
me wrong, I don't want to say that "D is unfinished" or "D has a 
bad design". I don't know it good enough to make such loud 
statements. I'm just trying to figure out what D is and how can I 
use it.

Answering your other question: I think that production ready 
language should have a "finished" design and its detailed 
description (not a basic overview of the features).
