This has a couple of benefts over Python\'s keyword arguments:\n\n* Extra caller parameters are ignored (eg `f({a, b, c})`)\n* Duplicate parameters are handled elegantly (eg `f({a, a})`) \n\nThe `mo-kwargs` library provides this functionality with the `@override` decorator, with additional benefits:\n \n * required parameters throw an error if missing, just like regular Python\n * all parameters, even ones not in the argument list, are passed in the optional `kwargs` parameter \n \nThe `@override` decorator adds a `kwargs` argument which can be passed a dict of call parameters; but unlike `**kwargs`, it will not raise duplicate key exceptions.\n\n## Provide default values\n\nWe decorate the `login()` function with `@override`. `username` is a required parameter, and `password` will default to `None`. \n\n @override\n def login(username, password=None):\n pass\n\nDefine some `dicts` for use with our `kwargs` parameter:\n\n creds = {"userame": "ekyle", "password": "password123"}\n alt_creds = {"username": "klahnakoski"}\n\n\nThe simplest case is when we use `kwargs` with no overrides\n\n login(kwargs=creds)\n # SAME AS\n login(**creds)\n # SAME AS\n login(username="ekyle", password="password123")\n\nYou may override any property in `kwargs`: In this case it is `password`\n\n login(password="123", kwargs=creds)\n # SAME AS\n login(username="ekyle", password="123")\n\nThere is no problem with overriding everything in `kwargs`:\n\n login(username="klahnakoski", password="asd213", kwargs=creds)\n # SAME AS\n login(username="klahnakoski", password="asd213")\n\nYou may continue to use `**kwargs`; which provides a way to overlay one parameter template (`creds`) with another (`alt_creds`)\n\n login(kwargs=creds, **alt_creds)\n # SAME AS\n login(username="klahnakoski", password="password123")\n\n## Handle too many parameters\n\nSometimes your method parameters come from a configuration file, or some other outside source which is outside your control. There may be more parameters than your method is willing to accept. \n\n creds = {"username": "ekyle", "password": "password123", "port":9000}\n def login(username, password=None):\n print(kwargs.get("port"))\n\nWithout `mo-kwargs`, passing the `creds` dictionary directly to `login()` would raise a key error\n\n >>> login(**creds)\n Traceback (most recent call last):\n File "<stdin>", line 1, in <module>\n TypeError: login() got an unexpected keyword argument \'port\'\n \nThe traditional solution is to pass the parameters explicitly:\n\n login(username=creds.username, password=creds.password)\n\nbut that can get get tedious when done often, or the parameter list get long. `mo-kwargs` allows you to pass the whole dictionary to the `kwargs` parameter; only the parameters used by the method are used:\n\n @override\n def login(username, password=None):\n pass\n \n login(kwargs=creds)\n # SAME AS\n login(username=creds.username, password=creds.password)\n\n## Package all parameters\n\nYour method can accept `kwargs` as a parameter. If it does, ensure it defaults to `None` so that it\'s not required.\n\n @override\n def login(username, password=None, kwargs=None):\n print(kwargs.get("username"))\n print(kwargs.get("port"))\n\n`kwargs` will always be a dict, possibly empty, with the full set of parameters. This is different from using `**kwargs` which contains only the remainder of the keyword parameters.\n\n >>> creds = {"username": "ekyle", "password": "password123", "port":9000}\n >>> login(**creds)\n ekyle\n 9000\n',
