    Checks whether the length of the `*args` argument passed into a function
    has at most `len(compat_args)` arguments and whether or not all of these
    elements in `args` are set to their default values.

    Parameters
    ----------
    fname : str
        The name of the function being passed the `*args` parameter
    args : tuple
        The `*args` parameter passed into a function
    max_fname_arg_count : int
        The maximum number of arguments that the function `fname`
        can accept, excluding those in `args`. Used for displaying
        appropriate error messages. Must be non-negative.
    compat_args : dict
        A dictionary of keys and their associated default values.
        In order to accommodate buggy behaviour in some versions of `numpy`,
        where a signature displayed keyword arguments but then passed those
        arguments **positionally** internally when calling downstream
        implementations, a dict ensures that the original
        order of the keyword arguments is enforced.

    Raises
    ------
    TypeError
        If `args` contains more values than there are `compat_args`
    ValueError
        If `args` contains values that do not correspond to those
        of the default values specified in `compat_args`

    Validate the keyword arguments to 'fillna'.

    This checks that exactly one of 'value' and 'method' is specified.
    If 'method' is specified, this validates that it's a valid method.

    Parameters
    ----------
    value, method : object
        The 'value' and 'method' keyword arguments for 'fillna'.
    validate_scalar_dict_value : bool, default True
        Whether to validate that 'value' is a scalar or dict. Specifically,
        validate that it is not a list or tuple.

        A single percentile or an iterable of percentiles.

    Returns
    -------
