Yeah, came here to say the same thing. Disappointing to have to write this:

    match shape:
        case Square(l):
            area = l * l
        case Rectangle(l, w):
            area = l * w
        case Circle(r):
            area = (PI * r) ** 2

when I want to just write this:

    area = match shape:
        case Square(l):
            l * l
        case Rectangle(l, w):
            l * w
        case Circle(r):
            (PI * r) ** 2

I'm almost guaranteed to forget (or mistype) the `area = ` at least once in any match clause of length.

That works almost exactly in Ruby. I really wish Python and Ruby would have a child.

Funny. Having worked extensively with Ruby and less so with Python, I think what I really want is expression-oriented Python.

Ideally as a next version of Python. But I think Julia and Nim come to mind as related to these concepts.
