'Produce a conjunction of expressions joined by ``OR``.
E.g.::
from sqlalchemy import or_
stmt = select([users_table]).where(
or_(
users_table.c.name == \'wendy\',
users_table.c.name == \'jack\'
The :func:`.or_` conjunction is also available using the
Python ``|`` operator (though note that compound expressions
need to be parenthesized in order to function with Python
operator precedence behavior)::
stmt = select([users_table]).where(
(users_table.c.name == \'wendy\') |
(users_table.c.name == \'jack\')
.. seealso::
:func:`.and_`'

@classmethod
def or_(cls, *clauses):

    return cls._construct(operators.or_, False_, True_, *clauses)
