--------------------------------------------------------------
[~julianhyde] We have not documented specifically for {{{}RelNode{}}}{{{}s,
whether a {{RelNode}}{}}} implements {{Hintable}} is kind of an interval
behavior and should be transparent to users, WDYT ? It's more valuable to
document about the general Hints syntax which we already have on the website.
BTW, more and more {{{}RelNode{}}}{{{}s implement {{Hintable}}{}}} we may need
to re-think the design about whether we should abstract out the {{Hintable}} as
base clazz for all the {{RelNodes}} for purpose of hints propagation or
something.
