The ABC Programming Language (homepages.cwi.nl)

There is a great documentary film about the origins of Python, which also talks about the ABC license, which influenced Python syntax (and the ABC project gave G. v. Rossum the job during which he created Python): https://www.youtube.com/watch?v=GfH4QL4VqJ0

Seems to be strongly influenced by HyperTalk... or is it the other way around?

Is it still mantained and instalable under current OSes?

Meta: this might benefit from a "(1987)" in the title, to clarify it's not a(nother) new language.

Not to be confused with the ABC music notation programming language
