Didn't exist at the time. While I still prefer scala to java 8, had the latter been available at the time I likely never would have dabbled in scala in the first place, if that makes sense
I dabble in what sorts of programming languages, but when comes to work, it is mostly C#, Java, JavaScript and some occasional C++, because that is what customers pay for.
Hence why I see a big value in mainstream languages slowly evolving into multi-paradigm ones, as many of us don't have the luxury to move beyond the first class languages of each platform.
