This is in reference to the recent PlotLegends -> “Expressions” question.
I filed a repot on this behavior with WRI tech support. A little later rcollyer posted an answer explaining it was new (undocumented) feature. This morning I received an answer from WRI tech support classifying it as a documentation issue.
I happen to think "documentation issues" are just as much bugs an code bugs, especially when they are as egregious as this one. But it might be confusing to tag such question with our current bugs tag. What does the community think? Do we need a new tag such as documentation-bugs?
