Yeah, and the use cases just aren't as strong in Python. I think part
of it is because a JS function taking keyword arguments looks like
this:
function fetch(url, options) {
const {method, body, headers} = options;
// ...
}
fetch("http://httpbin.org/post";, {method: "POST", body: "blah"});
whereas Python would spell it this way:
def fetch(url, *, method="GET", body=None, headers=[]):
...
fetch("http://httpbin.org/post";, method="POST", body="blah");
So that's one big slab of use-case gone, right there.
