> but it's even more frustrating to have to copy/paste code because your language doesn't have the abstraction facilities that let you factor out commonality.

I find this statement to be less of a problem in many modern programming languages (or greatly exaggerated by a specific language fan when comparing his/her preferred tools vs "the other languages).

I think in higher-kinded types these days, and can't stand to use a language without them (where I necessarily end up copy-pasting). There are plenty of modern languages without that.

I've only had to copy-paste code because of Scala's lack of support for polykinded code a few times, but it was very frustrating every time. Hardly any languages, even modern ones, support that.
