A Panoramic Tour of Factor (2015)

I was under the impression Factor had been abandoned, but it seems things are pretty lively on git:

Oh so slava pestov is not in Swift's team https://github.com/slavapestov?tab=contributions&from=2016-0...

I haven't played with it in years... I forget how seductive Factor is to think about.

I always go back to it to try something I've done in another language. I have not attempted anything big with it, but that is due to my concatenative language skills rather than any limitation by Factor.

Another take on this (for Forth and concatenative languages in the abstract): https://news.ycombinator.com/item?id=11377604

Is Factor similar to Q or KDB, ie APL-like?
