.. py:function:: ak.with_parameter(array, parameter, value, *, highlevel=True, behavior=None, attrs=None)


    :param array: Array-like data (anything :py:obj:`ak.to_layout` recognizes).
    :param parameter: Name of the parameter to set on that array.
    :type parameter: str
    :param value: Value of the parameter to set on that array.
    :type value: JSON
    :param highlevel: If True, return an :py:obj:`ak.Array`; otherwise, return
                  a low-level :py:obj:`ak.contents.Content` subclass.
    :type highlevel: bool
    :param behavior: Custom :py:obj:`ak.behavior` for the output array, if
                 high-level.
    :type behavior: None or dict
    :param attrs: Custom attributes for the output array, if
              high-level.
    :type attrs: None or dict

This function returns a new array with a parameter set on the outermost
node of its :py:obj:`ak.Array.layout`.

Note that a "new array" is a lightweight shallow copy, not a duplication
of large data buffers.

You can also remove a single parameter with this function, since setting
a parameter to None is equivalent to removing it.
