Others worth mentioning are Kotlin, Ada, Pascal, Haskell, Zig, Erlang, Elixir, Prolog, Ocaml.

Former EU, there's Gleam.

Kotlin is from St Petersburg, it's even named after an island near it.

St. Petersburg is in Europe.

I thought what was worth mentioning was being European or not, rather than being part of an European legal entity or not.

PHP is also from Europe. Not sexy perhaps, but popular enough to mention.

How is Zig an EU language?

Andrew started the language while he was in Germany.

Sadly, I’m old enough to remember that Ada was the result of a US initiative to standardize a capable language for embedded development.

A good friend worked on the well regarded Telesoft compiler…

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.
