Thank you for responding. I probably agree with the widget library example, but even here a widget library is just one way of implementing a GUI toolkit and perhaps it’s just the emergent result of an OOP-based approach (and consequently there are some really brutal tradeoffs in using a widget-based approach for a toolkit). To that point, with respect to general drawing libraries, I don’t think that OOP/inheritance yields a more elegant design than a reactive or intermediate mode approach (perhaps these terms only apply to GUI, but I imagine there are parallel terms for graphical APIs in general). Even though I concede narrowly on the widget GUI library point, these libraries are so very rare that I don’t think it’s a very compelling case for OOP proponents. I suspect they’d like to argue that there are appropriate uses for inheritance in most applications and not just the odd GUI library. Otherwise I don’t think it even merits first-class language support (why bother with an `extends` keyword if it’s only going to be useful in the rarest of libraries?).
