Python. Python is the most popular language designed in EU. EPFL is not even in EU
Others worth mentioning are Kotlin, Ada, Pascal, Haskell, Zig, Erlang, Elixir, Prolog, Ocaml.
True to both. My brain not braining. Was thinking Europe-based/driven. Python started in CWI but PSF is USA-based.
> EPFL is not even in EU
For people who don't get this, EPFL is the Swiss Federal Technical Institue in Lausanne. Switzerland isn't part of the EU or EEA but has instead integrated itself with the EU very closely via a mindboggling number of bilateral agreements with the EU members and the Schengen agreement which allows for free, borderless movement. This has the effect of making it seem very much like they are part of the EU without actually being as such.
