I'm looking at this as well. I'm confused about the word `figure` here. It looks like it's a keyword for this new type of pattern matching switch. but the word `figure` itself seems unneeded.

`figure` here is just an instance of Shape that was previously in scope. You've got to match on an instance of an object in this syntax.

It looks like "switch" is an infix operator in this context, so "figure" is just the variable/value on which the match operates.
