def literal(value, type_=None):
    r"""Return a literal clause, bound to a bind parameter.

    Literal clauses are created automatically when non-
    :class:`.ClauseElement` objects (such as strings, ints, dates, etc.) are
    used in a comparison operation with a :class:`.ColumnElement` subclass,
    such as a :class:`~sqlalchemy.schema.Column` object.  Use this function
    to force the generation of a literal clause, which will be created as a
    :class:`BindParameter` with a bound value.

    :param value: the value to be bound. Can be any Python object supported by
        the underlying DB-API, or is translatable via the given type argument.

    :param type\_: an optional :class:`~sqlalchemy.types.TypeEngine` which
        will provide bind-parameter translation for this literal.
