RE: [css-grid] proposal for repeat to take a third argument for jointure

Thinking about the argument of Array..join. This is for interblock spacing. (sorry I sent this on my phone, please excuse html)

Can you give some actual examples of where you'd want something like this?

Also, it's very unclear to me why you chose the precise definition you
did.  Wouldn't it be (int - 2) in the expanded version?  Can you
explain your reasoning?

Also, what's "jointure"?  Wikipedia's definition
<https://en.wikipedia.org/wiki/Jointure> doesn't seem relevant.
