I see that @narimiran changed the date - does that mean this is going to be posted soon?

This article currently advertises "safe to use" quite a lot. But did we fix enough bugs in std/channels? Maybe we should use a more conservative wording if we're not fully confident yet. See e.g. nim-lang/Nim#17392

The new channels library is efficient and safe to use

Why even say this? It implies that it has a reputation as not being safe to use. Just omit this wording completely, the assumption is that libraries are safe to use when they are being advertised as "ready for use".

1. All the examples in the article use globals for channels, what's worse, the only example in the module docs does the same. I understand it's the simplest way, but shouldn't we say a couple of words on how to properly use them without global variables?

2. Is the article planned to be released when channels gets out of devel? Will the old one get deprecated simultaneously? In any case, there should be an explicit mention on how to adapt the code which uses system.Channel to the new one, even if it's mere Just remove X,Y and Z and you're done!

Since the channel module may be rewritten/redesigned, this article will become a bit irrelevant. So I mark it as a draft.

Yes, I am in process of re-writing the module as the old one has a lot of problems including one or two data races. It's almost finished. When it has been accepted, I'll revisit this to see if this document reflects what the actual module has become.
