I've written about this before, but here's the summary:
There will be a comment thread on every single function in the 
standard library where people will say whatever they want and we 
can't stop them ahead of time.

- Anything they could possibly post there that's legitimately 
worth having would be better off canonised in the docs in the 
first place.
- Any questions they ask would be better asked on D.learn.
- Any other post may be subtly incorrect, previously correct, 
incredibly unsafe, correct with caveats, or a multitude of other 
shades of wrong.
- Everything else is noise.

We'd be better off wikifying the whole lot of it, and I don't say 
that lightly.  At least then there's the possibility of it being 
clear what's changing and who is changing it.
