To be fair, they have executed the overall project very well from what I've seen. A few things falling through the cracks is probably inevitable. That issue's not closed so there's hope for it yet.

OK, here's the expanded text for my comment (I didn't "show something" or disagree/agree -- I just provided reference):

"Here's this issue in Go bug tracker: https://code.google.com/p/go/issues/detail?id=65

Providing a link to the issue in the bugtracker, with discussion, is definitely "showing something".

I don't know, maybe I'm just weird, but when I see a comment replied to with a single link patterns suggest that it's a link disproving something. So I got confused until I had read the full page.
