How to use the yaql.language.specs.name function in yaql

@specs.name('type')
@specs.parameter('object_', dsl.MuranoObjectParameter(nullable=True))
def type_legacy(object_):
    return None if object_ is None else object_.type.name

@specs.name('name')

@specs.parameter('string', yaqltypes.String())
@specs.parameter('format__', yaqltypes.String(True))
def datetime_from_string(string, format__=None):
    if not format__:
        result = parser.parse(string)
    else:
        result = DATETIME_TYPE.strptime(string, format__)
    if not result.tzinfo:

    return result

@specs.name('keys')
@specs.method
def dict_keys(d):
    """:yaql:keys

    Returns an iterator over the dictionary keys.

    :signature: dict.keys()
    :receiverArg dict: input dictionary
    :argType dict: dictionary
    :returnType: iterator

    .. code::

        yaql> {"a" => 1, "b" => 2}.keys()
        ["a", "b"]
    """

@specs.name('#operator_.')
def collection_attribution(collection, attribute, operator):
    """:yaql:operator .

    Retrieves the value of an attribute for each element in a collection and
    returns a list of results.

    :signature: collection.attribute
    :arg collection: input collection
    :argType collection: iterable
    :arg attribute: attribute to get on every collection item
    :argType attribute: keyword
    :returnType: list

    .. code::

        yaql> [{"a" => 1}, {"a" => 2, "b" => 3}].a

@specs.name('replace')
def replace_string(string, regexp, repl, count=0):
    return replace(regexp, string, repl, count)
