Easy to guess the current content about the GC. If a person knows 
anything about the situation and has a small amount of 
imagination, all of this is totally obvious. What a mess!

Do we really have to reverse engineer the implementation to get 
here? And a very incomplete reverse engineering indeed. The 
blog's conclusion: The situation is bad, therefore avoid 
interacting with it --- this is my first order approximation to 
the article.

So about D itself. No design here then, no intent, no 
anticipation of the consequences of putting the pieces together, 
no strategic reasoning about the consequences of the construction 
of D with a garbage collector. All this long-ago stuff is coming 
home to roost.

The article admits it is incomplete. But what can follow except 
workarounds if someone needs to get past this? And most won't 
work. This is not just a roadblock. It reveals the entropy inside 
D. The core of D is fatally flawed. D is not a language where 
system garbage is taken care of, both concretely and abstractly. 
The idea that we all system-program ourselves around these 
difficulties suggests both labor and depression.

So disappointed. I wanted D to win. But this is where the dirt 
is, and I do not believe a strategic fix will ever be in the 
works. Entropy rules.
