I've heard this advice, like how they can't be called inside maps, etc, and I politely disagree. I think the power they represent should not be simply tossed out because they are harder to use. At least right now, I'll take the power along with the increased complexity for my side projects until such time as I see they are not worth it. (I'm not writing them into any production code, for what's it's worth)
