I’m mostly seeing a lot of Python. The examples show that multiple assignment unpacks collections, functions can be called with argument name assignment, and collections can be unpacked into named arguments, as opposed to using collections to replace named arguments.

Ruby supports that too. Here's a snippet that shows named arguments, and unpacking a Hash into named arguments.

It can do multiple assignment and unpacking collections into them too, though unlike with named arguments, that will treat the collection as an Array:

    def foo bar:, baz:
        p [bar, baz]
    end
    
    h = {bar: 1, baz: 2}
    
    foo(h)
