| Jun 5, 2021 at 5:40 | comment | added | Dewi Morgan | This sounds programmatically fraught. We want Square to be passable to any fn that takes any quadrilateral that Square can be. But this breaks: Rectangle.getTwoLongestSides() returns a pair of opposite sides. We could pick two arbitrary sides, but that assigns an orientation to Square that it should not have. And Kite.getTwoLongestSides() is expected to return two adjacent sides, so what do we do then? By allowing Square to be other things, we have to handle all these bizarre edge cases. Square has properties the others don't, and vice versa: it's just a bad fit for inheritance. | |
