Elixir, seriously: https://elixir-lang.org/install.html
I will add though, that Elixir does add some nice things besides just a more familiar syntax. Things like their string implementation stand out as a real improvement.
I will say a lot of it does feel dated & crusty though, especially when digging thru the documentation. And the different forms of iodata, list, binaries, bitstrings, and other string-y things is super confusing in the beginning.
As other people have said, there are no big new ideas in Elixir, it's just a well executed design in all the details. It also has the advantage of the tooling having been built from the ground up to current state of the art. As such, it is lovely to use.
The standard library benefits similarly. For example the '|>' operator in Elixir benefits from the fact that the standard library has a consistent argument order.
