This part is truly strange. This example from the tutorial drove it home for me:

    match event.get():
        case Click(position=(x, y)):
            handle_click_at(x, y)
        case KeyPress(key_name="Q") | Quit():
            game.quit()

where `Click(position=(x, y))` is not at all what one would expect.

What I still don't understand is: does the new syntax magically do this to a user-defined class? i.e. if I say

    foo = Click(position=(x, y))

vs

    ...
    case Click(position=(x, y))

those identical expressions, for the same value of Click, have widely different semantics?
