Sorry for hijacking the thread, but I actually was going to ask something about this a few days ago, so let's use this reference from Glyph as a starting point instead :)

It's not the first time I'm hearing that there are problems/and or limitations with inlineCallbacks, and I don't think I ever read somewhere what they were exactly? And so, each time I'm seeing code using inlineCallbacks, I'm frowning then realizing I have no idea why I did... Is there some place where I could find more information about these problems/limitations? That would be enlightening.
