In case you’re wondering what Lua does in this case, it has a special syntax iff the sole argument is a “table” (core dict/array mix) or a string: f {1, 2, a=3} is equivalent to f({1, 2, a=3}) A function f(t) receives an argument t in both cases. This makes a good use for DSLs by reducing ()-noise. It doesn’t have **kwargs in pythonic form, although it has varargs syntax. But all parameters are strictly positional and don’t self-pack or self-unpack in any way. So this inspiration is pretty far from what happens there.
